WebThe purpose of this paper is to investigate radiative and magnetic effects on entropy generation in thermosolutal convection with heat and mass transfer flow in 2D approximation for both aiding and opposing buoyancy forces, which is in our knowledge, has not been studied yet. Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. WebApr 7, 2015 · For a natural convection problem, this is done by calculating the Grashof number, Gr.
