Unsteady Magnetohydrodynamic (MHD) flow past an accelerated vertical plate in the presence of thermal radiation and chemical reaction

Abstract

A study on Magnetohydrodynamic (MHD) flow past an accelerated vertical plate with the effects of thermal radiation and chemical reaction has been carried out. The dimensionless governing equations are solved using Laplace transform technique. The solution for the velocity, temperature and concentration field are obtained and analyzed for the different physical parameters like thermal Grashof Number, Modified Grashof Number, permeability parameter, Prandtl Number, Radiation parameter, Schmidt Number, chemical reaction parameter and time. It is observed that the velocity profile increases with increasing parameters like, Sc, Gc, M, R and t and also decrease with the decreases Pr and Gr. the temperature profile shows the decrease with the decreasing in Pr and t. and increase in R. While the concentration profile shows the increase in alpha and decrease in Sc and t.
