Abstract: The purpose of this study is to analyze the magnetohydrodynamic mixed convection flow of an incompressible, conducting, elastico-viscous fluid (characterised by Walters’ model B') past a vertical, permeable, infinite plate in the presence of heat source/sink parameter, thermal radiation, and first-order chemical reaction with account for an induced magnetic field and Soret effect. The governing flow equations are solved by perturbation technique, and the expressions are obtained for velocity field, temperature field, induced magnetic field, and concentration field. The effects of visco-elastic parameter, Soret number, heat source/sink parameter, Hartmann number, magnetic Prandtl number, and chemical reaction parameter on the flow characteristics have been studied. Results show that velocity enhances with an increase in magnetic Prandtl number, heat source/sink parameter, and Soret number, but it decreases with an increase in Hartmann number, chemical reaction parameter, and visco-elastic parameter. Increasing heat source/sink parameter and chemical reaction parameter escalate the temperature within the boundary layer. Induced magnetic field, Nusselt number and skin friction are found as decreasing functions of magnetic Prandtl number whereas induced magnetic field is an increasing function of visco-elastic parameter, and Nusselt number is an increasing function of Soret number. |
Keywords and phrases: perturbation technique, elastico-viscous fluid, induced magnetic field, Soret number.
