About this Research Topic
In science, phenomena involving multiple scales in time and/or space are of crucial importance in several fields. In engineering, physics, chemistry, meteorology, transport processes, and computer science we can find very complex multiscale phenomena which require deep study to improve our civilization. In the same context, it is also possible to find more scientific domains involved in several typical scales of the phenomenon. This produces a strong challenge for the new generation of scientists.
Such phenomena are ubiquitous in nature, biological systems and a wide range of industries, including biomedical, chemical, energy and process engineering. They often involve complex interactions with other physical and/or chemical processes, such as turbulence, combustion, heat transfer and phase change. In a diesel engine, for example, fuel spray is injected into a highly unsteady, turbulent, high-temperature and high-pressure mixture of gases. In this case, multiple scales are clearly present in time and the accurate modeling of the turbulent microscales interaction, for example, can drastically improve the the mixing efficiency and so the global efficiency of the entire thermodynamic cycle, with an impact on a longer time-scale.
In this Research Topic we intend to collect a number of high quality papers treating the main issues of multiscale/multiphysics phenomena with particular emphasis on their computational modeling. Therefore, typical solution and coupling algorithms, as well as physicochemical models, should be mainly addressed in the papers.
Submissions devoted to engineering interest problems are welcomed. For example, turbulence, fluid-structure interaction, multiphase flows and interface phenomena, urban flows, aeroacoustics, molecular dynamics, mass transport, combustion, magnetohydrodynamics (MHD), electrohydrodynamics (EHD), nanofluids, and so on are of interest for this Topic.
