摘要

An analysis is presented to study the effects of radiation on the hydromagnetic free convection flow (set up due to temperature as well as species concentration) of an electrically conducting micropolar fluid past a vertical porous plate through porous medium in slip-flow regime. A uniform magnetic field acts perpendiculary to the porous surface which absorbs the micropolar fluid with variable suction velocity. The Rosseland approximation is used to describe the radiative heat flux in energy equation. The numerical results of velocity distribution of micropolar fluids are compared with the corresponding flow problems for a Newtonian fluid. Assuming variable permeability of the medium, numerical results are presented graphically in the form of velocity, micro rotation, and temperature profiles for different material parameters entering into the analysis. Also, the results of the skin-friction coefficient, the couple stress coefficient, the rate of heat and mass transfers at the wall are discussed with the help of figures.
