MHD Flow Past a Parabolic Started Isothermal Vertical Plate with Variable Mass Diffusion in the Presence of Chemical Reaction of First Order.

Laplace transform solution of MHD flow past a parabolic starting motion of the infinite isothermal vertical plate with variable mass diffusion, in the presence of homogeneous chemical reaction of first order has been studied. The plate temperature is raised uniformly and the concentration levels near the plate are raised linearly with time. The effect of velocity, temperature and concentration profiles are studied for different physical parameters like chemical reaction parameter, thermal Grashof number, mass Grashof number, Schmidt number and time. It is observed that the velocity increases with increasing values the thermal Grashof number or mass Grashof number. The trend is just reversed with respect to the chemical reaction parameter as well as magnetic field parameter.
