Abstract—Thermal radiation effects on unsteady flow past an uniformly accelerated infinite vertical plate with variable temperature and uniform mass diffusion, under the action of transversely applied magnetic field has been presented. The plate temperature is raised linearly with time and the concentration level near the plate is also raised to ω C′ . The dimensionless governing equations are solved using Laplace-transform technique. The velocity profiles, temperature and concentration are studied for different physical parameters. It is observed that the velocity increases with increasing values of thermal Grashof number or mass Grashof number. It is observed that the velocity increases with decreasing magnetic field parameter or radiation parameter.

Index Terms—Accelerated, isothermal, radiation, vertical plate, heat transfer, mass diffusion, magnetic field.
