EXACT SOLUTION OF FLOW PAST AN ACCELERATED INFINITE VERTICAL PLATE WITH UNIFORM HEAT AND MASS FLUX

摘要

An exact solution of an unsteady flow past an uniformly accelerated infinite vertical plate with prescribed uniform heat and mass flux is analyzed. The temperature of the plate and concentration level near the plate are raised at a uniform rate. The dimensionless governing equations are tackled using the usual Laplace-transform technique. The velocity, temperature and concentration fields are studied for different physical parameters such as the Prandtl number, thermal Grashof number, mass Grashof number, Schmidt number and time. It is observed that the velocity increases with increasing values of the thermal Grashof number or mass Grashof number. It is also observed that the velocity increases with decreasing values of the Schmidt number.
