Soret Effect on Stagnation-Point Flow Past a Stretching/Shrinking Sheet in a Nanofluid-Saturated Non-Darcy Porous Medium

Abstract

The significance of the Soret effect on the boundary-layer stagnation-point flow past a stretching/shrinking sheet in a nanofluid-saturated non-Darcy porous medium is investigated in this study. The nanofluid-saturated porous medium is considered by incorporating the Brownian motion and thermophoresis effects. A similarity transformation is used to reduce the governing fluid flow equations into a set of differential equations and then solved numerically by an accurate implicit finite-difference method. The flow; temperature; concentration and nanoparticle concentration fields; skin friction coefficient; and heat, mass, and nanoparticle mass transfer rates are affected by the complex interactions among the various physical parameters involved in the analysis. These profiles are illustrated graphically in order to reveal interesting phenomena.

Nanofluid Transport in Porous Media: A Review

“…The effects of the rotation, AC electric Rayleigh number, Lewis number, concentration Rayleigh number, modified diffusivity ratio, and porosity on the stability of the system were investigated for the stationary convection. RamReddy et al (2016) investigated in this study contribution of the significance of the Soret effect on the boundary-layer stagnation-point flow past a stretching/shrinking sheet in a nanofluid-saturated non-Darcy porous medium. The flow; temperature; concentration and nanoparticle concentration fields; skin friction coefficient; and heat, mass, and nanoparticle mass transfer rates were affected by the complex interactions among the various physical parameters involved in the analysis.…”

Double Stratification in the Flow of a Newtonian Fluid Along an Inclined Permeable Stretching Surface

“…Pal and Hiremath [5] considered an unsteady stretching surface and performed computational modelling of heat transfer. Also, in a nanofluid saturated non-Darcy porous medium, Soret effect on stagnation-point flow over a stretching/shrinking surface is discussed by RamReddy et al [6]. The different analyses related to boundary layer flow over an inclined stretching sheet have acquired considerable importance in last a few years due to its involvement in many important applications for various sectors of industries and engineering, e.g., as in production of papers, glass-fibre, drawing of wire and plastic films, in order to cool the metallic sheets using cool bath, etc.…”
