Abstract: 

An analysis is carried out to investigate the effects of radiation and chemical reaction on an unsteady, laminar, natural convective flow of a micropolar fluid past a moving vertical porous plate in the presence of porous medium. A first order chemical reaction and radiation has been considered in the study. The free stream velocity follows an exponentially increasing or decreasing small perturbation law. The method of solution can be applied for small perturbation approximation. The various values of permeability, chemical reaction parameter, radiation, Schmidt number, Prandtl number, viscosity ratio, thermal Grashof number, mass Grashof number on velocity, angular velocity, temperature and concentration are presented graphically. A comparative study between Newtonian fluid and non-Newtonian fluid is also presented. It is observed that an increase in either the radiation or the chemical reaction decreases the velocity. An increase in radiation effect decreases the thermal boundary layer. The concentration boundary layer decreases with an increase in the chemical reaction and Schmidt number.
