Analyzing thermophoresis phenomenon in a transient free convective MHD chemically radioactive fluid over oscillatory permeable media

A numerical observation of chemically radioactive free convective magneto hydrodynamics fluid passing through a vertical permeable medium with fluctuating mass and heat transfer with thermophoresis is studied here. The fluid type is assumed to be a suspended mixture of particles that are incompressible, chemically strong, ionized, and viscous with some mass infusibility. The model pertaining to this problem is resolved through the application of a highly stable implicit finite difference method. The method is used for small and large deflections of the physical parameters, which result in a noticeable fluid flow behavior depicted graphically. The momentum, energy, concentration, skin friction, Nusselt and Sherwood number are investigated for various factors such as the thermophoresis effect, magnetic field, permeability, and chemical reaction rate. The substantial findings of the present investigation indicate that the impact of thermophoresis is more pronounced in the diffusion of concentration as compared to the rate of chemical reactions. The concentration is considerably influenced by the permeability parameter, surpassing the influence of the chemical reaction rate. For higher radiation parameters and Prandtl number, the molecular interaction of liquids increases, which in turn constrains the extent of radiative heat exchange. [GRAPHICS]
