Abstract

This investigation deals with the combined effects of Navier slip, suction/injection, convective cooling and temperature dependent viscosity on an unsteady third grade fluid flow in a porous channel filled with saturated porous medium. The heat exchange with the ambient at the channel surfaces is assumed to obey Newton’s law of cooling. The model equations governing the flow system are solved using a semi-implicit finite difference scheme. The effects of the thermophysical parameters on the temperature and velocity fields, the skin friction and the wall heat transfer rate are simulated and discussed in detail. Keywords: third grade fluid, Navier slip, suction/injection, temperature dependent viscosity, convective boundary conditions.
