Influence of Chemical Reaction and Soret Effect on Mixed Convective MHD Oscillatory Flow of Casson Fluid with Thermal Radiation and Viscous Dissipation

Abstract

In this paper the effects of thermal radiation, chemical reaction and Soret number on magnetohydrodynamic heat and mass transfer of a Casson fluid in the presence of magnetic field and viscous dissipation are analyzed. Perturbation technique has been used to convert the governing nonlinear partial differential equations into a ordinary linear differential equation and then solved analytically. The effects of physical parameters on velocity, temperature and concentration profiles are analyzed by plotting graphs and compared the present results with previously published results. It is observed from the results that the velocity profile increases with increase in the chemical reaction, thermal Grashof number and mass Grashof number but the opposite trends are seen with increase in the magnetic field parameter, Prandtl number and Schmidt number. Also, there is a tendency to increase the value of skin friction coefficient and the local Nusselt number with an increase in the Casson fluid parameter.
