This communication analyzes the dual convection regime of Newtonian fluid flow in a Y shaped porous enclosure with heat and mass distribution, using a mathematical model of dimensionless PDEs and an effective finite element method. The top curved wall of the enclosure is assumed hot and side walls are cold while the bottom wall is assumed adiabatic. The problem is discretized using P2 and P1 finite element methods to approximate the displacement, pressure, and velocity. The linearized system of equations is solved using Newton’s iterative scheme. The study evaluates the impact of key parameters such as the Hartmann number, Lewis number, Rayleigh number, and buoyancy ratio on the flow, heat transfer rate, and mass transfer rate. Results indicate that an increase in the Hartmann number, Rayleigh numbers and buoyancy ratio amplifies both mass and heat transfer rates. The buoyancy ratio has a noteworthy impact on the flow and transfer rates, with a greater influence seen for. The study presents graphical representations of flow and temperature fields, as well as Nusselt and Sherwood numbers provide a comprehensive visualization of the results. Heat and mass transfer rate is minimum for concentration dominated counter flow (N=2) and maximum for concentration dominated assisting flow N=2.

1 Introduction

The interaction between mass and heat transfer is a common occurrence observed in both natural and industrial settings. An interesting consequence of this interplay arises when a fluid experiences simultaneous gradients in both temperature and concentration, resulting in the emergence of a complex and intricate fluid flow pattern, referred to as double diffusive convection. This phenomenon has long fascinated the scientific and engineering communities, owing to its far-reaching implications in numerous fields, such as oceanography, geophysics, energy transport, and materials science. To obtain a more comprehensive understanding of this phenomenon, delving into some of the crucial foundational works is imperative [13]. Later on several authors had noticed the occurrence of doubly diffusive natural convection (DDNC) [4] effects of a fluid within a porous material [5, 6] with a high Rayleigh number [7] and transition between oscillatory and steady convection [8]. The transport of heat and mass in double diffusive natural convection is closely linked, as the fluid flow induced by the temperature and concentration gradients affects the transport of both heat and mass. Kumar etal [9]. Conducted a numerical investigation to examine the transport of flow, heat, and mass in a rectangular cavity with partially heated walls. He employed the Lattice Boltzmann Method (LBM) as a numerical technique to solve the fluid flow problems involving single and multi-phase systems. Furthermore, he recommended conducting additional experiments to visualize the application of LBM in heat and mass transfer. The phenomenon of double diffusive convection has been studied extensively by various researcher AA Farooq [10]. The phenomenon of double diffusive convection has been studied extensively by various researchers. Han and Kuehn [11] looked at how the temperature and concentration gradients applied horizontally would affect a vertical rectangular cavity. They concluded that a complicated temporary multi-structural formation can be seen during the concurrent transfer of heat and mass in a rectangular container under both supporting and opposing buoyancy circumstances. The study conducted by Beghein et al. [12] focused on exploring the consequences of steady-state thermosolutal convection in a square cavity, while Mamou et al. [13] analyzed a numerical and analytical model for natural convection in a rectangular cavity containing a double-diffusive fluid, with uniform heat and mass flux along the vertical sides. Nikbakhti and Rahimi [14] conducted a computational analysis of the fluid dynamics, thermal dynamics, and mass transfer in a rectangular chamber where the walls were heated partially. He obtained results for different heating conditions and parameters, also measured the heat and mass transfer rates to determine the mean Sherwood and Nusselt numbers. The researchers discussed DDNC in a rectangular [15], trapezoidal [16, 17], irregular [18], trapezoidal with fillets [19], and hexagonal [20, 21] enclosure. While Walker and Homsy [22] investigated natural convection driven by buoyancy in a porous square cavity where one of the horizontal sides was differentially heated. The study concluded that non-uniform heating of the bottom wall produces a higher heat transfer rate at the centre of the bottom wall compared to the uniform heating case. Furthermore, the study determined that conduction is the primary mechanism for heat and mass transfer, and established critical Rayleigh numbers for dominant cases, as well as a correlation between average Nusselt number and Rayleigh numbers.

Porous media have found wide-ranging applications in different fields, owing to their exceptional characteristics and features. Even though Mamou et al. [23] analyzed the commencement of the double-diffusive convection phase inside a rectangular porous channel, while Karimfard et al. [24] analyzed the occurrence of double-diffusive natural convection in a squared porous cavity. Some of the fluid-flow models that the researchers looked into were the Forchheimer and Brinkman additions, the Darcy flow, and the extended flow. In a similar way, Nithiarasu et al. [25] used analytical methods to study double-diffusive flow in a rectangular cavity, while Bennacer and others [26] used numerical simulation methods to study how soaked asymmetrical porous materials affect this kind of convection. Anand Rao et al. [27] cast-off the finite element method to study the flow of a rotating fluid across an infinite flat porous plate when a magnetic field and Hall current were present. He found that fluid flows in plate at constant angular velocity and the primary and secondary velocity fields are in non-dimensional form. Researchers [2831] have used the finite element method to explore the influence of mass and heat transfer on the dynamics of suction-driven, vertically oscillating plates in unstable magneto hydrodynamic flows. Ramana Murthy et al. [32]. Looked at the effects of mass and heat transmission on instable MHD regular convection stream over an infinite vertical plate in a porous environment warmed by thermal radiation. A well-known author [33] examined the transfer of heat and mass while discussing the blood flow through a narrow artery with stenosis. He investigated that the presence of gold (Au) nanoparticles (NPs) in Oldroyd-B nanoliquid flow affects stenosis arteries under the influence of MHD. Taklifi and Aliabadi [34] did an analytical study of the stream of a non-Newtonian fluid over a permeable layer when the magneto hydrodynamic (MHD) conditions were unstable. Taza et al. [35] presented a numerical model that investigates and compares the behavior of simple and hybrid nanoparticles on a spreading surface. The work on stretching surface was discussed by zahr shah [36, 37]. Abdullah et al. [38] studied about ceramic materials, i.e., Alumina. As a result, the author has developed a mathematical equation to describe the mixed convective flow of nanofluid contain Alumina nanoparticles past a stretching surface in three dimensions under magnetohydrodynamic condition.

Rashad and El-Kabeir [39] studied a diverse flow of convection over a vertically strained sheet immersed inside a fluid-saturated porous media under the impact of a chemical reaction effect to study the associated mass and temperature transport processes under transient conditions. Noor Fadiya et al. [40] used the Adomian decomposition method along with Padé approximants to solve the magneto hydrodynamic boundary-layer stream caused by a transparent stretching sheet submerged in a porous material. The problem was effectively and precisely solved using this method. An analysis of Co-current convection and radiation phenomena around an impermeable inclined plate, subject to magneto and thermal radiation effects in a porous medium, was performed by Orhan and Ahmet [41]. Zahir et al. [42] studied irreversibility in steady water-based nanofluid flows between two rotating disks using the Darcy–Forchheimer relation, constant temperatures/velocities, and a radial/tangential magnetic field. They proved that the radial velocity component is increased with the Reynolds number and decreased with the porosity parameter and inertial coefficient, while the tangential velocity component and temperature profile are reduced with the Reynolds number and increased with the Hartmann number and nanoparticle volume fraction. Mukesh Kumar Sharma et al. [43] examined a non-Darcian permeable material containing an electrically charged, viscous, and appropriate solvent trapped between two indefinitely long, horizontal, impermeable plates and the relatively stable magneto hydrodynamic flow and heat exchange properties of this system. Both viscous as well as Joule absorption characteristics were taken into account in the analysis. The mixed convective stream along an inclined surface inside a permeable material filled with Newtonian fluid was analyzed by Mansour et al. [44]. The magneto hydrodynamic circulation of an incompressible level commensurate over porous materials was studied by Masood Khan et al. [45], who found perfect solutions to the problem. Hayat et al. [46] looked at magneto hydrodynamic flow, utilizing Laplace as well as Fourier sine transform techniques to derive steady-state and transient solutions. Das et al. [47]. Studied the effects of Hall and thermal radiation on an unsteady magneto hydrodynamic convective flow that vibrates via a porous medium contained in a vertical plate. Its effect of mass transport upon the magneto hydrodynamic circulation of two compressible fluids under the influence of a chemical reaction as they flow across a translucent stretching sheet in a porous medium was studied by Abbas et al. [48]. The unsteady, oscillatory flow of a magneto hydrodynamic flow through a rectangular channel packed with an absorbent medium that is flooded, as well as the accompanying thermal transfer properties, were studied by Ahmer et al. [49]. The effect of a wall’s temperature that is not consistent with the rest of the surface was also taken into account in the study. Ahmet and Sezer [50]. Provided an analytical solution for the constant, two-dimensional, turbulent, forced magneto hydrodynamic Hiemenz flow that occurs against a flat board with a changing wall temperature in a permeable material. The study employed the homotopic perturbation method to arrive at the solution. Well-known author Mahmood [51] incorporated a variety of visual representations, including 2D plots, to illustrate the acquired solutions Based on an assessment of the previously mentioned scientific studies, the spreading occurrence in non-newtonian fluid as a result of thermal and solutal buoyancy propelled forces has not been explored. Moreover, in spite of the significant increase of magnetic fields in numerous contemporary engineering systems, such characteristics are rarely analyzed collectively. Consequently, the aim of this undertaking is to address this deficiency by introducing non-newtonian fluid with thermal and solutal limitations on the right wall of the cavity. In order to achieve this, the mathematical formulation of the problem is represented as a partial differential equation, and subsequently, similarity parameters are utilized to transform PDEs [52] into ODEs. A numerical solution to the formulated problem is obtained through the utilization of finite element methodology in simulation. Ultimately, crucial parameters’ impacts on associated distributions are illustrated in a visual and tabulated layout.

In the initial section of this paper, the inspiration and rationale behind the research are explained, along with an extensive discussion of the relevant references and literature. In Section 2 of the paper, the mathematical equation that governs DDNC in fluid-saturated porous media is thoroughly described. This section offers a detailed explanation of the underlying physical phenomena that drive the DDNC process. The dimensionless form of the Navier-Stokes equations is solved using FEM. In Section 3 of the paper, the proposed method’s accuracy and effectiveness are showcased through a detailed presentation of the numerical approach and validation methodology. In Section 4, the outcomes are visually presented through streamlines, isoconcentration and isotherms plots, depicting the influence of the variables on the heated and cooled regions. Section 5 summarizes the results of the analysis conducted in this study.

2 Mathematical model

2.1 Problem description

We have considered the fluid flow that is laminar, uniform, incompressible, and flowing in two dimensions inside a Y-shaped cavity with circular cylinder inside. When the left and right side cavity wall is affected by cooling temperature Tc with low concentration CC) and wall of a top-side cavity is subjected to a high temperature (Th)while the concentration (Ch)of the gas in the cavity is increased, and vice versa. The cavity’s remaining components are meant to be adiabatic. It was determined that a magnetic field with a strength of B should be imposed at an angle of degrees to the horizontal. These equations are discretized all around the cavity with the help of the unstructured mesh. Figure 1A shows the flow issue, while Figure 1B shows the unstructured mesh sketch shape.

3 Numerical scheme

Exact procedures are useful for dealing with fluid flow behavior in the absence of limited barriers, but it is challenging to find the solution in a closed cavity with obstacles of varying forms and sizes using only those approaches. Hence, most researchers use numerical systems to publish their findings, with FEM, FDM, and FVM among the most common approaches. One of the most flexible of these numerical methods is the FEM, which is used to discrete elements to simulate complicated and irregular geometries on a flat domain. Fluid, heat and mass transfer movement inside of enclosures have served as the focus of a significant amount of research using computational methods. Using the finite-element method (FEM), the above leading Eqs. 110 are discretized. Then Newton’s Raphson iteration approach is applied to the nonlinear algebraic equations. The flowchart in Figure 2 shows FEM’s basic process.

The parameters retain their typical definitions, and in order to obtain the solution, the non-linear system is iteratively processed until a certain threshold of tolerance is reached.

3.2 Verification and investigation of grid dependency

To validate the efficiency of the achieved consequences, Table 1 displays the results of using several grids with the parameters Ha=20, Ra=1e5, Pr=6.8, and Le=2. As a direct consequence of this, the number of degrees of freedom (DOFs), and the number of elements (NEL), can range anywhere from (6424 191,996) and (598 21124), respectively. Variations between Sherwood and Nusselt numbers are almost indiscernible in the final two grids (8, 9). The grid-independent numerical findings are thus provided using DOFS 168196 and NEL of 18324.

4 Result and discussion

In this section, we will compare the findings of the study in the form of streamlines, temperature profile, and isoconcentration patterns to a variety of physical parameters. This involves Ra (Rayleigh number), N (buoyancy ratio), Ha (Hartmann number), Le (Lewis number) and Da (Darcy number). The obtained mass flux coefficients (Sherwood numbers) and heat flux coefficients (Nusselt numbers) are of significant importance, in terms of their wider applicability and their local relevance.

The dispersion of streamlines, temperature profile, and isoconcentrations at different Ra are shown in Figure 3. The results show that an increase in the Ra results in a stronger natural convection, causing notable changes in fluid velocities, temperature, and concentration distributions. The impact of the Rayleigh number on natural convection and its related heat and mass transfer properties is noticeable. Due to the temperature gradient between the top, left, and right walls, the fluid within the system circulates from the region with higher temperature to the cooler areas.

Figure 4 displays the streamlines for varying buoyancy ratios. Natural convection and the related flow dynamics are seen to be significantly affected by the buoyancy ratio. When buoyancy ratio is negative (concentration dominated counter flow), fluid flows mostly from the warm to the cool side of the cavity, creating two convection cells. As the buoyancy ratio approaches zero (thermal convection dominated flow), the 2 cells become increasingly symmetric, and the flow becomes more uniform. At higher buoyancy ratios (concentration dominated assisting flow), the flow pattern becomes more complex, with extra vortices forming in the cavity. So when buoyancy ratio becomes negative, as seen in part 2 of Figure 4, the fluid closest to the top wall heats up, while the fluid near its bottom wall cools down. As buoyancy ratio approaches zero, the temperature distribution becomes increasingly symmetric, and the heat transfer becomes more uniform. At higher buoyancy ratios, the temperature distribution becomes more uniform. In the third part the Isoconcentration behave same as Isotherms.

FIGURE 4. Profiles of momentum, temperature, and solute against buoyancy ratio.

Figure 5 shows how Da affects the mass as well as heat transmission properties of natural convection. As can be seen in this diagram, Da has a major impact on the distributions of both temperature as well as concentration. When Darcy’s number goes down, its temperature closest to hot wall goes up, while the temperature close to the cold wall falls down. The same is true for concentration, which gets better as it gets closer to the top of the wall and worse as it gets closer to the bottom. Moreover, the concentration distribution becomes more uniform as the Darcy number decreases.

FIGURE 5
www.frontiersin.org

FIGURE 5. Profiles of momentum, temperature, and solute for different Darcey number.

In Figure 6, we see how the streamlines, isotherms, and concentrations vary for various Hartmann numbers. When the Hartmann number rises, its magnetic field becomes stronger, resulting in increased suppression of fluid motion, and hence reduced rates of thermal and mass transfer. The figure reveals this phenomenon as the streamlines start pointing in the same direction as the magnetic field and the fluid flow is restricted to the bottom of the cavity. Further it also shows that the temperature and concentration distributions become more uniform as the Hartmann number increases, which is caused by suppressed temperature and concentration gradients and decreased fluid velocity.

Figure 7 shows the relationship between the Nusselt number and the Sherwood number as a function of the Rayleigh number for a range of Darcy numbers. When the Darcy number goes down, the rate of heat and mass transfer goes down. For all Darcy numbers, it is seen that a rise in the Rayleigh number results in a corresponding increase in the Nusselt number.

FIGURE 7. Effect of Da and Ra on the mean Nusselt number and mean Sherwood number for Pr = 6.8, Ha = 20, N = 2.

Figure 8 illustrates how the Rayleigh number affects the heat and mass transfer for variation of Hartmann numbers. Heat and mass transfer rate is minimum for pure hydrodynamic case (Ha=0) and increase for increasing values of Hartmann number. This influence of magnetic field strength on heat and mass transfer rates can be better understood with the help of above illustration. As the Rayleigh number rises, the Sherwood and Nusselt numbers also rise gradually, as shown in the figure.

FIGURE 8. Effect of Ha and Ra on the mean Nusselt number and mean Sherwood number for Pr = 6.8, Ha = 20, N = 2.

Figure 9 is a chart that illustrates the Sherwood and Nusselt numbers as a consequence of the Rayleigh number for a variety of buoyancy ratios (−2, 0, 2). Heat and mass transfer rate is minimum for concentration dominated counter flow (N=2) and maximum for concentration dominated assisting flow (N=2).

Figure 10 presents a statistical analysis of the relationship between heat and mass transfer considering variation in the Darcy number and Rayleigh number. The heat transfer rate is visually represented by blocks, whereas the variation in mass transfer is illustrated by lines. The result indicates a discernible increase in both heat and mass transfer for higher values of the Darcy number (Da) and Rayleigh number (Ra), as visually observed in the figure.

Table 2 presents numerical data on the Hartmann number (0Ha40), Darcey number (102Da104), Rayleigh number (1e5Ra1e7), Lewis number (1Le10), and buoyancy ratio (2N2) for mean Nusselt number (Nu) and mean Sherwood number (Sh). It is observed that at fixed parameter Ha=20,Da=0.01,Ra=e5,Le=2,N=2, the mean Nusselt number (Nu) is 2.7998 and the mean Sherwood number (Sh) is 0.9758. The data shows that the highest values for the mean Nusselt number and mean Sherwood number is observed at a Rayleigh number (Ra=1e7) with magnitude 7.0651 and 2.3072 respectively where the other parameter are fixed.

The problem is formulated mathematically using system of dimensionless PDEs. An effective FEM is used to handle modified partial differential systems. The domain is discretized using quadrilateral and triangular elements at multiple level. The LBB-stable element provides as close approximation of the velocity, temperature and concentration. These results could be used to improve the design of heat transfer systems, cooling systems, and other engineering parts.

• Increase in the Hartmann number, Buoyancy ratio and Rayleigh numbers amplifies both the heat and mass transfer rates.

• The natural convection becomes stronger as the Rayleigh number increases, leading to higher fluid velocities and significant changes in the temperature and concentration distributions.

• The Darcy number significantly affects the temperature and concentration distributions, with decreasing Darcy number resulting in increased temperature near the hot wall and increased concentration near the top wall.

• For concentration dominated counter flow heat and mass transfer rate decreases for the variation in Ra (Rayleigh number).

• For concentration dominated assisting flow mass and heat transfer rate increases for the variation in Rayleigh number.
