Radiation Effect on MHD Unsteady Free Convective Viscoelastic Fluid with Constant Suction and Heat Sink

Abstract

The present study is unsteady hydromagnetic free convective memory flow of incompressible and electrically conducting fluid past an infinite vertical porous plate in the presence of radiations with constant suction and heat absorbing sink have been discussed. Approximate solutions have been derived for the mean velocity, mean temperature, mean skin-friction and mean rate of heat transfer using multi-parameter perturbation technique. The obtained results are discussed with the help of graphs to observe that the effect of various parameter like Prandtl number, Magnetic parameter and Radiation parameter.
