Hall effects on MHD free convective flow and mass transfer over a stretching sheet

TL;DR

This paper investigates the effects of Hall current and magnetic fields on heat and mass transfer in MHD free convection flow over a stretching sheet, using numerical solutions of transformed boundary layer equations.

Contribution

It introduces a numerical approach to solve non-linear boundary layer equations considering Hall effects in MHD flow over a stretching sheet.

Findings

Velocity, temperature, and concentration profiles are affected by magnetic and Hall parameters.

Skin-friction coefficient, Nusselt number, and Sherwood number vary with nondimensional parameters.

Numerical results are presented graphically for different parameter values.

Abstract

Of concern in this paper is an investigation of heat and mass transfer over a stretching sheet under the influence of an applied uniform magnetic field and the effects of Hall current are taken into account. The non-linear boundary layer equations together with the boundary conditions are reduced to a system of non-linear ordinary differential equations by using the similarity transformation. The system of non-linear ordinary differential equations are solved by developing a suitable numerical techniques such as finite difference scheme and Newton's method of linearization. The numerical results concerned with the velocity, temperature and concentration profiles as well as the skin-friction coefficient, local Nusselt number Nu and the local sherhood number Sh for various values of the nondimensional parameters presented graphically.
