CHEMICAL REACTION EFFECTS ON FLOW PAST AN ACCELERATED VERTICAL PLATE WITH VARIABLE TEMPERATURE AND MASS DIFFUSION IN THE PRESENCE OF MAGNETIC FIELD

An exact solution to the problem of unsteady hydromagnetic flow past a uniformly accelerated infinite vertical plate with variable temperature and mass diffusion are presented, taking in to account the homogeneous chemical reaction of first order. The plate temperature as well as the concentration level near the plate increased linearly with time. The dimensionless governing equations are solved using Laplace-transform technique. The velocity, temperature and concentration fields are studied for different physical parameters like thermal Grashof number, mass Grashof number, Schmidt number, Prandtl number, magnetic field parameter, chemical reaction parameter and time. It is observed that the velocity increases with increase of thermal Grashof number and mass Grashof number. It is also observed that the velocity increases with decrease of chemical reaction parameter as well as magnetic field parameter.
