Heat Transfer to Magnetohydrodynamic Non-Newtonian Couple Stress Pulsatile Flow Between two Parallel Porous Plates

Abstract

This paper investigates the effect of radiative heat transfer to oscillatory hydromagnetic nonNewtonian couple stress fluid flow through a porous channel with non-uniform wall temperature due to periodic heat input at the heated wall. Based on some simplifying assumptions, the dimensionless partial differential equations are transformed into a set of ordinary differential equations and then solved using the Adomian decomposition method. The effects of the flow parameters on temperature and velocity profiles are shown graphically and discussed

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

“…Zelalem et al, [10] discussed the fluid flow and heat transfer of couple stress fluid through parallel walls endowed with extended porous materials. Interested readers can see [11][12][13][14][15][16] for more significant results on couple stress fluid flow.…”

Effects of Thermal Radiation on MHD Peristaltic Motion of Walters-B Fluid with Heat Source and Slip Conditions

“…heating and freezing of chambers, fossil fuel combustion energy processes, evaporation from massive open water reservoirs, propulsion devices for aircraft, missiles, satellites and space vehicles etc. Keeping in mind the importance of such applications investigated by several authors in (Adesanya and Makinde 2012;Seth et al 2015a;Seth et al 2015b;Seth et al 2016) Although in the peristaltic flow problems fewer attentions have been focused to analyze the flows in the presence of a slip condition. The application of slip condition in the peristaltic flows has special importance in physiology and polymers.…”

Entropy Generation Rate in Unsteady Buoyancy-Driven Hydromagnetic Couple Stress Fluid Flow Through a 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]. 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.…”

“…For instance, Shercliff [5] investigated the steady motion of an electrically conducting viscous fluid along channels in the presence of an imposed transverse magnetic field when the walls do not conduct currents. Adesanya and Makinde [6] studied the effect of radiative heat transfer to oscillatory hydromagnetic non-Newtonian couple stress fluid flow through a porous channel with non-uniform wall temperature due to periodic heat input at the heated wall. In a related work, Reza and Gupta [7] examined the flow of a combination of incompressible viscous electrically conducting fluids in the presence of a transverse uniform magnetic field.…”
