• THE EFFECT OF CHEMICAL REACTION ON UNSTEADY HEAT AND MASS TRANFER FLOW PAST AN EXPONENTIALLY ACCELERATED VERTICAL PLATE WITH VARIABLE TEMPERATURE AND MASS DIFFUSION

Abstract

An exact solution to the problem of unsteady flow past an infinite vertical exponentially accelerated plate with variable temperature and mass diffusion has been presented here, taking into account the homogeneous chemical reaction of first order. The plate temperature is raised linearly with time and species concentration level near the plate is also raised linearly with respect to time. The dimensionless governing equations involved in the present analysis are solved using Laplace-transform technique. The velocity, temperature and concentration fields are studied for different physical parameters like Thermal Grashof number (Gr), Mass Grashof number (Gm), Schmidt number (Sc), Prandtl number (Pr), accelerated parameter (a), chemical reaction parameter (K) and time (t) with the help of graphs.
