Injection and suction effects on three-dimensional unsteady flow and heat transfer between two parallel porous plates.

Abstract

The problem of unsteady three-dimensional flow of an incompressible viscous fluid between two horizontal parallel porous plates with transverse sinusoidal injection of the fluid at the stationary plate and with constant suction through the plate in uniform motion has been studied. The moving plate is kept at oscillating wall temperature while the stationary plate is at constant temperature. Analytical expressions for velocity, temperature, and rate of heat transfer are obtained and discussed with the help of graphs and tables.
