Exact solutions for three fundamental unsteady flows of an incompressible couple stress fluid between two parallel plates, namely, Couette, generalized Couette and Poiseuille flows, are obtained. Analytical solutions of the corresponding initial-boundary value problems are obtained by means of the integral transforms method (Laplace and finite sine Fourier transforms). For each flow type, the solution is written as the sum between the post transient solution (steady-state solution) and the transient solution. The volume flow rate and skin friction coefficients are, also, obtained. The effect of various parameters on the fluid velocity is graphically underlined and discussed and the critical time to reach the steady-state is also determined.

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 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. Recently, Srinivasacharya and Kaladhar [12] considered the Soret and Dufour effects in the presence of chemical reaction on natural convection heat and mass transfer of a couple stress fluid in a vertical channel.…”

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.
