Entropy generation analysis for a reactive couple stress fluid flow through a channel saturated with porous material

Numerical Study of Nonlinear Heat Transfer from a Wavy Surface to a High Permeability Medium with Pseudo-Spectral and Smoothed Particle Methods

“…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].…”

Irreversibility analysis for a mixed convective flow of a reactive couple stress fluid flow through channel saturated porous materials

“…As shown in [6], Kaladhar et al, described the forced convective flow of reactive couple stress fluids undergoing destructive chemical reaction. Adesanya et al [7] reported the inherent irreversibility in the couple stress fluid flow through horizontal channel. Asad et al [8], highlighted the significance of the flow and heat transfer of couple stress fluid having temperature-dependent thermal conductivity.…”

Entropy Generation Rate in Unsteady Buoyancy-Driven Hydromagnetic Couple Stress Fluid Flow Through a Porous Channel

“…Adesanya and Falade [9] analysed the inherent irreversibility in the flow of hydrodynamic third grade fluid through a channel saturated with porous materials. Other important studies in this direction include [10,11,12,13,14,15,16,17,18,19] However, none of the references mentioned above on the analysis and entropy generation of non-Newtonian couple stress magnetohydromagnetic fluid flow has considered the analysis of entropy generation rate in magnetohydrodynamic couple stress fluid flow in porous channel. In reality, non-Newtonian couple stress fluid are used as working fluids in many technological and industrial processes, including polymer technology, petroleum industry [20].…”

“…In reality, non-Newtonian couple stress fluid are used as working fluids in many technological and industrial processes, including polymer technology, petroleum industry [20]. Motivated by studies in [6,7,8,9,21,10,11,12,13,14,15,16,17,18,19], the objective of the present study is to examine the influence of magnetic field and Ohmic heating of the couple stress fluid on the entropy production within the flow channel, which has not been accounted for in the literature. The outcoming results is expected to enhance many industrial and thermal engineering processes whose working medium is non-Newtonian fluid, with a view to minimise entropy generation which tends to deplete the amount of available energy for work.…”
