“…The results of these investigations will be communicated in the near future. Furthermore the present work may also be extended to electrically-conducting fluids in order to address magnetohydrodynamic, slip, dissipative and possibly entropy generation effects, as considered by Adesanya and co-workers [58][59][60][61][62].…”

“…The possibility of a reduction of entropy generation in a viscous convection cooling system has been reported for a double face structure [9,14,16]. Several analyses have been conducted on the irreversibility of the entropy generation as a result of reactive flow in a channel [17][18][19][20][21][22][23][24][25][26][27]. Collocation method has likewise been used to obtain heat generation force of convective flow through permeable walls.…”

This paper studies convective heat transfer in an unsteady vertical porous channel with suction/injection in the presence of heat generation. A semi-implicit finite difference method was employed to solve the Cartesian coordinate forms of the governing equations. Subsequently, the entropy generation number for varying values of intrinsic parameters, as well as the temperature and velocity profile, Bejan number and irreversibility of the system were successfully calculated. We observed that the convective cooling by suction is more effective on thermal properties than injection convective cooling. Hence, the process of entropy can be enhanced by convective heat transfer and viscous dissipation. ARTICLE HISTORY

“…Later, Makinde and Mhone [8] extended the work of Takashima [4] to an isotropic porous domain case and subsequently to an anisotropic porous domain by Shankar and Shivakumara [9]. In the past, the stability of conducting fluid flows in a channel in the presence of a uniform magnetic field has attracted the attention of a host of researchers (Takashima [10], Kaddeche et al [11], Balyaev and Smorodin [12], Adesanya et al [13], Hayat et al [14], Hudoba et al [15], Hudoba and Molokov [16], Bhatti et al [17], Shankar et al [18], Ijaz et al [19], Hassan et al [20], Shankar et al [21] and references therein).…”

The effect of a uniform vertical magnetic field on the stability of pressure-driven flow of an electrically conducting non-Newtonian fluid in an isothermal channel is numerically investigated using the Chebyshev collocation method. The non-Newtonian fluid is modeled by the couple stress fluid theory, which permits for polar effects and encountered regularly in liquids with very large molecules. It is established that Squire's theorem is valid and the modified Orr-Sommerfeld equation is derived by considering the fact that the magnetic Prandtl number P m , for recognized electrically conducting liquids is too small. The triplets (R c , α c , c c), where R c is the critical Reynolds number, α c is the critical wave number and c c is the critical wave speed, are obtained for different values of couple stress parameter Λ and the Hartman number M. It is found that increasing M has a stabilizing effect on the system while an increase in the couple stress parameter shows twofold deeds. Individual aspects of the kinetic energy spectrum are observed and presented for different parametric values to obtain comprehensive information at the critical state of fluid flow.
