Abstract
A numerical analysis of unsteady magnetohydrodynamic (MHD) flow over a vertically oscillating plate within a porous medium is presented, incorporating the effects of heat sources and the Soret phenomenon. The coupled, nonlinear dimensionless governing equations were solved using an implicit finite difference method. Graphical representations of the velocity, temperature, and concentration profiles derived from the numerical solutions are provided and discussed. The impact of various physical parameters such as the magnetic field parameter, radiation parameter, Schmidt number, Prandtl number, Grashof number, heat source parameter, and Soret number is illustrated through graphs. It was observed during the computations that increasing the heat source parameter enhances both the fluid velocity and temperature, whereas increasing the magnetic field parameter results in a decrease in these quantities. Additionally, higher Soret number values lead to increases in both fluid velocity and concentration.Keywords: Unsteady flow, Porous medium, MHD, Heat source, Implicit finite difference
