Newtonian Heating and Mass Transfer Effects on Free Convection Flow past an Accelerated Vertical Plate in the Presence of Thermal Radiation

The unsteady free convection flow past an infinite vertical plate with Newtonian heating has been studied in
the presence of thermal radiation for a uniformly accelerated plate and an exponentially accelerated plate. The problem
is solved under the conditions of (i) uniform wall concentration (UWC) and (ii) uniform mass flux (UMF) by Laplace
transform technique. Closed form analytical expressions for the velocity and the skin-friction are obtained for various
cases. It is observed that an increase in the buoyancy ratio parameter leads to a decrease in the skin-friction.
