Abstract
We investigate the effects of thermo-diffusion (Soret number) and diffusion-thermo (Dufour number) on hydromagnetic steady flow past a rotating disk in a porous medium with Hall current. The governing equations are transformed into a system of ordinary differential equations and solved using the successive linearization method (SLM). The effects of the magnetic interaction parameter, Soret number, Dufour number, Schmidt number, Prandtl number, and suction or injection parameter on the fluid velocity, temperature, and concentration distributions in the regime are depicted graphically and are analyzed in detail. The skin-friction coefficients for some parameters are also calculated and displayed in tables showing the effects of various parameters.
