An analysis of the unsteady flow of an incompressible fluid past an uniformly accelerated infinite vertical plate has been presented in the presence of variable temperature and mass diffusion. The temperature of the plate as well as concentration near the plate are made to raise linearly with time. The dimensionless governing equations are tackled using Laplace-transform technique. The velocity, the temperature and the concentration fields are studied for different physical parameters like Schmidt number, thermal Grashof number, mass Grashof number and time. It is observed that the velocity increases with increasing values of thermal Grashof number or mass Grashof number. It is also observed that the velocity increases with decreasing values of the Schmidt number.

Keywords: linear, accelerated, vertical plate, heat transfer, mass diffusion,unsteady.
