Abstract

In this research paper, we numerically analyzed the effects of Soret and magnetic field on radiating and chemically reacting MHD unsteady free convective flow past an exponentially accelerated inclined permeable plate embedded in a saturated porous medium of uniform permeability with variable temperature and concentration numerically. The model's dimensionless coupled non-linear PDEs are solved numerically by using the finite difference method. The influence of key parameters on the velocity, temperature and concentration fields are discussed graphically whilst the numerical results of skin-friction, Nusselt and Sherwood numbers are exhibited in tabular form. The results obtained show that the permeability of the medium, thermal and mass buoyancy force improves the fluid velocity whilst the magnetic field and inclination angle have reverse effect. The fluid velocity and temperature decreases with an increment in radiation parameter whilst the reverse trend is observed in case of Nusselt number. The Soret effect is to elevate the fluid velocity and concentration whilst chemical reaction rate has reverse impact and these parameters have opposite effect on the Sherwood number. This flow model has various industrial applications in the field of food processing, polymer production, inclined surfaces in a seepage flow, design of fins, etc.
