Effects of Unsteady Flow Past An Infinite Vertical Plate With Variable Velocity, Temperature and Constant Mass Flux

Abstract

The effects of unsteady flow past an infinite vertical plate with variable temperature and constant mass flux are investigated. Laplace transform technique is used to obtain velocity and concentration fields. The computation of the results indicates that the velocity profiles increase with increase in Grashof numbers, mass Grashof numbers and time. For combined parameters, the velocity field is increasing with increase of mass Grashof number and decreases with increasing Grashof, Schmidt and Prandtl numbers. Similarly, concentration profile is decreasing with increasing Schmidt number.

Keywords: unsteady flow, infinite vertical plate, variable temperature, constant mass flux.
