MHD Heat and Mass Transfer on Stretching Sheet with Variable Fluid Properties in Porous Medium

Abstract

An analysis is carried out on steady two dimensional stagnation point flow of an incompressible conducting viscous fluid with variable properties over a stretching surface embedded in a saturated porous medium. The flow model is subjected to (i) transverse magnetic field, (ii) variable viscosity and thermal conductivity, (iii) thermodiffusion (Soret effect), (iv) stretching of both plate and free stream (v) pressure gradient in the flow direction is considered non-zero. The Runge-Kutta fourth order method with a self corrective procedure i.e. shooting technique has been applied to solve the governing equations. An interesting result of the analysis is that inversion in formation of velocity boundary layer is due to reversal in stretching ratio. On the other hand, heat transfer leading to formation of thermal boundary layer is not affected significantly. Variable thermal conductivity enhances the temperature distribution. Increase in concentration difference and thermophoresis parameter gives rise to thinner solutal boundary layer. Further, it is remarked that heavier chemically reactive species enhance the rate of solutal transfer at the surface.

“…profile increases with while temperature and Swain et al [20] presented the MHD heat and mass transfer on a stretching sheet with variable fluid properties in a porous medium and concluded that variable thermal conductivity enhances the temperature reactive fluid flows is playing an practical purpose and relevant sign, geochemical and the dynamics of fog and mist of temperature and moisture trees, damage of crops due to freezing, evaporation at the interface of water an be classified to be either homogeneous or heterogeneous process. Cussler s one that occurs phase whereas heterogeneous reaction is one that occurs in a restricted area or within the order of the chemical reaction depends on many factors.…”

Heat transport and stagnation‐point flow of magnetized nanoliquid with variable thermal conductivity, Brownian moment, and thermophoresis aspects

“…This is very essential when working with products that produce heat, such as electronic gadgets and fire and heat safety materials. Some remarkable work has been done by Chiam, 17 Swain et al, 18 Reddy et al, 19 and Hamid et al 20 past a stretching sheet with consideration of variable fluid properties. Sharma and Singh 21 considered the MHD flow near a stagnation point past a linearly stretching sheet.…”

A Study on MHD Nanofluid Flow and Heat Transfer with Convective Surface Temperature and Concentration

“…Magnetohydrodynamics (MHD) nanofluid flow on a stretching sheet is of great interest in the field of engineering and technology especially extrusion of polymer sheet from expire, aerodynamic extrusion of plastic sheets, geothermal systems etc. Swain et al [1] have studied the MHD heat and mass transfer on stretching sheet with variable viscosity as well as thermal conductivity. The thermo-diffusion has also been taken care of.…”
