The present work examines the effect of temperature-dependent fluid density on the reactive couple stress fluid flowing steadily in a vertical channel saturated with porous materials. The thermal effect gave rise to a linked differential system of equations. In the dimensionless form, the boundary-valued problems (BVP) are uncoupled and solved by using Adomian decomposition method (ADM). The solutions are used to obtain expressions for entropy generation and Bejan heat irreversibility number in the porous medium. The relevant fluid parameters are varied and discussed physically. The present result shows good agreement with the previously obtained result when buoyancy force is neglected. The present study is relevantal in the thermal treatment of combustible fluids in chemical and petro-chemical engineering.

“…Makinde and Eegunjobi [9] studied the inherent irreversibility in a steady flow of a couple stress fluid through a vertical channel packed with saturated porous substances. Makinde and Adesanya [10] investigated the entropy generation in couple stress fluid flowing steadily through a porous channel filled with slip at the isothermal walls. Adesanya and Makinde [11] examined the effect of couple stresses on the entropy generation rate of an incompressible viscous fluid through a porous channel with convective heating at the walls.…”

In this paper, entropy generation rate in the flow of couple stress fluid undergoing exothermic chemical reaction through a porous vertical channel is studied by applying the second law of thermodynamics. A semi-analytical solution for the governing equations is obtained using Adomian decomposition method (ADM). The effects of couple stress parameter, internal heat generation parameter, Dufour number on the velocity, temperature distribution, entropy generation rate and Bejan number are investigated and the results were presented graphically. The results show that solutal diffusivity has significant effect on the entropy generation rate and irreversibility of heat in a couple stress fluid flow.

The present work addresses the entropy generation in the flow of an incompressible viscous fluid through porous parallel walls subjected to asymmetric slip and convective heating conditions. The differential equations for momentum and energy are formulated, made dimensionless, solved and used to compute the entropy generation rate in the flow channel.The effect of various physical parameters on the velocity, temperature and entropy generation profiles are presented graphically and discussed.
