Effects of Chemical Reaction on MHD Flow Past an Impulsively Started Infinite Vertical Plate with Variable Temperature and Mass Diffusion in the Presence of Hall Current

Abstract

In this paper, the effects of chemical reaction on unsteady MHD flow of viscous incompressible

electrically conducting fluid past an impulsively started oscillating vertical plate with variable

temperature and constant mass diffusion in the presence of Hall current have been presented. The

dimensionless governing partial differential equations of the flow have been solved numerically

by using the Crank-Nicolson implicit finite difference scheme. The numerical solutions for

primary fluid velocity, secondary fluid velocity, fluid temperature and fluid concentration are

plotted graphically whereas the numerical results of primary skin friction, secondary skin

frictions, rate of heat and mass transfer are presented in tabular form for various parameters

involved. A comparison has been provided between the present results and with the existing

analytical solutions by the Laplace transforms technique. It has been found that the results of the

present study are in excellent agreement with previously obtained results.
