Abstract

An exact solution of flow past an exponentially accelerated infinite vertical plate and temperature has been presented in the presence of variable mass diffusion. The dimensionless governing equations are solved using Laplace transform technique. The velocity, temperature, and concentration profiles are studied for different physical parameters like radiation parameter R, accelerating parameter a, thermal Grashof number Gr, mass Grashof number Gc, chemical reaction parameter K, Prandtl number Pr, Schmidt number Sc and time t. It is observed that the velocity increases with increase in Gc, Gr, R, a, Pr, Sc and t. It is also observed that temperature rise with increasing t, a, R while concentration increases with increasing t.
