About this Research Topic
Experimental approaches are widely considered as the main source of information for predicting the physical behavior of fluids. However, due to the complexities in fluid behavior, especially in the case of multi-physical flows where the time and length scales vary significantly, experimental means become either extremely expensive or in some cases impossible. Under these constraints, scrutinizing physical phenomenon seems to be possible only when alternative tools are available, such as Computational Fluid Dynamics (CFD).
This Research Topic welcomes the comparisons of conventional CFD techniques such as Finite Difference (FDM), Finite volume (FVM) and Finite Element (FEM) simulations of complex flows to elaborate on their differences, similarities, advantages and drawbacks. The development and validation of less established, novel numerical methodologies such as Smoothed Particle Hydrodynamics (SPH), Discrete Element (DEM), Moving Particle semi-Implicit (MPS) and Lattice Boltzmann (LBM) methods also fall within the scope of this Research Topic.
Papers ranging from new physical models and discoveries to the correct treatment of difficulties inherent to numerical modeling of fluid flow systems will be considered. These include but are not limited to:
• Submissions which effectively model physical boundary conditions;
• Submissions on mass and energy conservation;
• Submissions that realistically treat complicated physical interfacial phenomena such as folding, merging and/or break-up;
• Submissions that take the interfacial jump condition into account (i.e. large density and viscosity ratios in multi-phase and/or compressible flows);
• Submissions that deal with more complicated phenomena such as those in Magnetohydrodynamics (MHD), Electrohydrodynamics (EHD), non-Newtonian flows, nano-fluidic, etc. problems; and finally;
• Submissions based on the extension of above-mentioned methodologies to three-dimensions and high performance computing (HPC).
