Entropy Generation Analysis for Porous Channel Flow with Asymmetric Slip and Thermal Boundary Conditions

Abstract

This study investigates the inherent irreversibility in the steady flow of viscous incompressible fluid through a channel with infinite parallel porous plates. The system is assumed to exchange heat with the ambient surrounding following the Newton’s law of cooling. Exact solution of the dimensionless governing equations are obtained and used to compute the entropy generation rate and the irreversibility ratio. The effects of slip and convective cooling parameters on the velocity, temperature and entropy generation profiles are presented and discussed extensively based on the physics of the fluid.
