Abstract
The objective of the present paper is to investigate chemical reaction effect on unsteady hydromagnetic free convection flow of a viscous, incompressible, electrically conducting fluid with heat and mass transfer past a moving porous vertical plate of infinite length with time dependent suction in the presence of heat source in a slip flow regime. Slip flow conditions for the velocity, jump in temperature and jump in concentration are taken into account in the boundary conditions. The governing equations involved in the present analysis are solved by perturbation technique. The velocity, temperature and concentration are studied for different parameters like Prandtl number, velocity ratio parameter, magnetic field parameter, chemical reaction parameter and slip parameter due to jump in concentration. It is inferred from the graphs that the temperature of the plate decreases with increasing the values of the Prandtl number. The concentration is decreased in the presence of chemical reaction and slip parameter due to jump in concentration.
