Heat and Mass Transfer in MHD Visco-Elastic Fluid Flow through a Porous Medium over a Stretching Sheet with Chemical Reaction

Abstract

This paper presents the study of convective heat and mass transfer characteristics of an incompressible MHD visco-elastic fluid flow immersed in a porous medium over a stretching sheet with chemical reaction and thermal stratification effects. The resultant governing boundary layer equations are highly non-linear and coupled form of partial differential equations, and they have been solved by using fourth order Runge-Kutta integration scheme with Newton Raphson shooting method. Numerical computations are carried out for the non-dimensional physical parameters. Here a numerical has been carried out to study the effect of different physical parameters such as visco-elasticity, permeability of the porous medium, magnetic field, Grashof number, Schmidt number, heat source parameter and chemical reaction parameter on the flow, heat and mass transfer characteristics.

Effect of Variable Viscosity, Dufour, Soret and Thermal Conductivity on Free Convective Heat and Mass Transfer of Non-Darcian Flow past Porous Flat Surface

“…Layek et al [3] considered the effects of thermal radiation and variable fluid viscosity on free convective flow and heat transfer past a porous stretching surface while, Alharbi et al [4] investigated the heat and mass transfer of MHD viscoelastic fluid flow through a porous medium over a stretching sheet with chemical reactions, due to the importance of Soret (Thermal-diffusion) and Dufour (Diffusion-thermo) effects on the fluids with very light molecular weight as well as medium molecular weight. Darcy's empirical flow model represents a simple linear relationship between flow rate and pressure drop in a porous media; any deviation from the Darcy flow scenario is termed non-Darcy flow.…”

Stagnation Point Flow and Heat Transfer of a Magneto-Micropolar Fluid Towards a Shrinking Sheet with Mass Transfer and Chemical Reaction

“…Muhaimin et al [14] considered the magnetohydrodynamic viscous flow due to a shrinking sheet in the presence of suction. Alharbi et al [15] investigated convective heat and mass transfer characteristics of fluid flow immersed in a porous medium over a stretching sheet with chemical reaction and thermal stratification effects. Muhaimin, et al [16] investigated the viscous flow due to a two dimensional and axisymmetric shrinking sheet in the presence of suction with variable stream conditions.…”

Unsteady MHD flow of a visco-elastic fluid along vertical porous surface with fluctuating temperature and concentration

“…Alhabi et al [10] have analyzed heat and mass transfer in MHD visco-elastic fluid flow through a porous medium over a stretching sheet with chemical reaction. Kumar and Sivraj [11] have studied MHD mixed convective visco-elastic fluid flow in a permeable vertical channel with Dufour effect and chemical reaction parameter.…”
