Natural convection heat and mass transfer in a micropolar fluidsaturated non-Darcy porous regime with Radiation and thermophoresis effects

Abstract

An analysis is presented for the steady thermal convection heat and mass transfer in a micropolar-fluid-saturated non-Darcian porous medium in the presence of radiation and thermophoresis effects. The governing boundary layer equations for momentum, energy, species transfer and angular momentum (micro-rotation) are transformed from an (x, y), coordinate system into (h), coordinate system. The influence of Darcy number (Da) , Forchheimmer number (Fs) , local Grashof number (Gr), Prandtl number (Pr) , Schmidt number (Sc), radiation (R) and thermophoresis (k), surface parameter (s), on the velocity, temperature, concentration profiles and angular velocity (micro-rotation) are studied graphically. Applications for the problem arise in chemical engineering systems and geothermal energy systems.
