Abstract
The present work investigates numerically the inherent irreversibility in a steady
flow of a couple stress fluid through a vertical channel packed with saturated porous
substances. The First and Second Laws of Thermodynamics are applied to analyze the
problem. The nonlinear governing equations in Cartesian coordinates are obtained and
solved numerically using shooting methods together with a Runge-Kutta Fehlberg
integration scheme. The entropy generation number is computed by utilizing the velocity
and temperature profiles. The effects of various physical parameters on the flow and heat
transfer characteristics, as well as entropy generation rates and Bejan number, are
investigated through graphs.
