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

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 co-ordinate system into h co-ordinate system. The influence of Darcy number, Forchheimmer number, local Grashof number, Prandtl number, Schmidt number, radiation, thermophoresis, and surface parameter 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.
