Abstract:
An exact analysis of the flow of an incompressible viscous fluid past an infinite vertical plate is conducted
taking into account the presence of foreign mass or constant mass flux and ramped wall temperature. The
dimensionless governing coupled linear partial differential equations are solved using the Laplace transform
technique. Two different solutions for the fluid velocity are obtained–one valid for the fluids of Schmidt
numbers different from unity, and the other for which the Schmidt number is unity. The effects of Prandtl
number (Pr), Schmidt number (Sc), time (t) and mass to thermal buoyancy ratio parameter (N) for both aiding
and opposing buoyancy effects on the velocity and skin-friction are studied. Also, the heat and mass
transfer effects on the flow near a ramped temperature plate have been compared with the flow near a plate
with constant temperature.
