Deep Investigation on Natural Convection Flow of a Couple Stress Fluid with Nanoparticles in an MHD Vertical Porous Channel with Convective Boundary Conditions

Abstract

This paper looks at the MHD natural convection flow through a vertical porous channel of couple stress fluid nanoparticles under convective heat conditions at the wall of the channel. Incorporated Soret and Dufour effects lead to strong coupled and highly nonlinear differential systems. To describe accurately all the physical phenomenon, the nanoparticle's volume fraction is taken into account. The useful technical of the similarity transformations is used to produce an ordinary system which is numerically solved. Graphical illustrations containing non-dimensional velocity, temperature, concentration and concentration of nanoparticles are extensively presented for different values of various thermophysical parameters. Main quantities of interest as Nusselt and Sherwood numbers at both the walls are tabulated.

Thermophoretic and Suction/blowing Effects on MHD Mixed Convection Flow over an Inclined Plate Combined with Heat Generation, Chemical Reaction and Radiation

“…Characteristics of viscous dissipation, Joule heating and convective boundary condition are analyzed with nanofluid flow. For examples, works of Prasad et al [20][21][22], Vaidya et al [23], for Casson nanofluid, Agha et al [24][25] and A.M Bouaziz et al [26] in porous dispersive medium, Tayeb and Bouaziz [27] for Couple stress nanofluid, take into account the thermophoresis mechanism. In another way, the peristaltic movement of physiological liquids becomes an emerged axis, Vaidya et al [28][29].…”
