Effect of Chemical Reaction on Unsteady Mhd Convective Transport Passing a Vertical Porous Sheet

Abstract

An analysis of the effect of chemical reactions on unsteady MHD convective transport passing a vertical porous sheet has been introduced in this research paper. The model formed of highly nonlinear governing equations are converted by inserting the similarity transformations. The numerical solutions of the fluid properties like concentration, temperature, and velocity are presented graphically. This paper also presented the heat transfer rate, mass transfer rate, and the local skin friction coefficient which are analyzed in tabular forms. The dimensionless parameters or numbers used in this problem are suction parameter, magnetic parameter, Prandtl number, Schmidt number, and chemical reaction parameter. Results give the improvement of concentration and motion of the fluid for growing values of the chemical reaction, but the reverse trends are found for the Schmidt number. The local skin-friction coefficient and the mass transfer rate are increased by about 23 % and 283%, respectively for growing amounts of the chemical reaction from 0.5 to 2.0.
