“…Interestingly, our new result shall be equivalent to that of HASSAN and MARITZ, 2016 a; when the porous medium permeability parameter (  ) and buoyancy effect parameter known as Grashof number ( Gr ) are both zero to validate the solutions obtained. Table 1 displays the rapid convergence of the series solution for the constants 0 a and 0 b in equations (10) and (11) which shows the efficiency and reliability of the modified ADM. It really signifies that the series converge with sizeable iterations.…”

The survey of buoyancy driven flow of a reactive hydromagnetic Poiseuille fluid flowing within porous channel with respect to a heat source produced internally is investigated. The coupled differential equations regulating the fluid flow are simplified by seeking the use of modified Adomian decomposition method (MADM) which is later presented in tables and graphs to show the effects of buoyancy force and various parameters included in the flow regime.

Irreversible losses and heat transport in a magnetohydrodynamic flow of a viscous, steady, incompressible, and fully developed couple stress Al 2 O 3-water nanofluid through a sloping permeable wall channel with porous medium and under the effect of radiation heat flux and slip were analyzed. The fundamental equations were solved numerically by using Runge-Kutta together with the shooting technique and the results were in qualitative agreement with an exact solution obtained for a limit case. The impacts of couple stress, Darcy number, solid nanoparticle concentrations, conduction-radiation parameter, Hartmann number and hydrodynamic slip on flow, temperature, heat transport, and entropy production were examined. It was possible to achieve values of minimum entropy production not yet reported in previous studies. In this way, optimal values of couple stress and slip were obtained. The heat transport was also explored and optimal values of slip flow and conduction-radiation parameter with maximum heat transfer were found. Finally, in addition to the alumina, the distributions of velocity, temperature, and entropy generation in TiO 2-water and Cu-water were presented for different solid nanoparticle concentrations. It was obtained that the local entropy of TiO 2-water was lower than Cu-water and Al 2 O 3-water in the channel bottom region while it was greater in the upper region.

“…Complexities arising from solving various couple stress fluid models and the wide application horizon has motivated many scholars to continue with active research in the couple stress fluid model. Hassan [10] used modified Adomian decomposition method to analyse a reactive hydromagnetic couple stress fluid flow through a channel filled with saturated porous media. Makinde and Eegunjobi [11] investigated the inherent irreversibility in a steady flow of a couple stress fluid through a vertical channel packed with saturated porous substances.…”

In this paper, the mixed convective flow of an electrically conducting, viscous incompressible couple stress fluid through a vertical channel filled with a saturated porous medium has been investigated. The fluid is assumed to be driven by both buoyancy force and oscillatory pressure gradient parallel to the channel plates. A uniform magnetic field of strength B0 is imposed transverse to the channel boundaries. The temperature of the right channel plate is assumed to vary periodically, and the temperature difference between the plates is high enough to induce radiative heat transfer. Under these assumptions, the equations governing the two-dimensional couple stress fluid flow are formulated and exact solutions of the velocity and the temperature fields are obtained. The effects of radiation, Hall current, porous medium permeability and other various flow parameters on the flow and heat transfer are presented graphically and discussed extensively.
