Abstract
The numerical solution of unsteady MHD fluid flow has been studied under the action of transverse magnetic field with radiation, diffusion-thermo, thermal diffusion and Hall current for small magnetic Reynolds number. The governing equations are non-dimensionalized by using usual dimensionless variables. The explicit finite difference technique has been used to solve the non-similar, coupled, nonlinear partial differential non-dimensional equations. Finally, the solutions of the dimensionless velocities, temperature and concentration equations are shown graphically as well as a qualitative comparison with previous work are also shown in tabular form.
