Entropy Generation Analysis in a Vertical Porous Channel with Navier Slip and Viscous Dissipation

Abstract

The intension of this paper is to investigate the effects of Navier slip and buoyancy force on the entropy in a vertical generation porous channel with suction/injection. This problem is solved analytically by perturbation technique. Closed form solutions are obtained for the fluid velocity and the temperature. The leads of slip parameter, injection/suction Reynolds number, Peclet number and Brinkmann number on the fluid velocity, temperature profiles, Bejan number, and rate of entropy generation are showed graphically and quantitatively discussed.
