Effects of soret, dufour, hall current and rotation on MHD natural convective heat and mass transfer flow past an accelerated vertical plate through a porous medium

Abstract

This article concentrates on the impact of Hall current, Radiation, Soret, and Dufour on an unsteady MHD Natural convective flow over an infinite vertical plate fixed in a porous media. The entire system is supposed to revolve with an unvarying angular velocity Ω′around the perpendicular to the plate and an unvarying transverse magnetic field is enforced along the normal to the plate which is coordinated in the fluid area. The solution of the non-deimensional governing equations along with the boundary conditions are solved by using effeicient Galerkin Method. The effect of different pertinent flow parameters on velocity, temperature, and concentration distributions and the numerical outcomes are examined and revealed graphically. With the increase of Sorent number the concentration profile increases and reverse trend is observed in the case of Dufour numbers. Comparision done with the recent work on exceptional instances of the problem is acquired and is seen to be in accord.
