Abstract
The study’s unsteady MHD free convective flow traverses a porous material that is influenced by thermal radiation, heat absorption, the hall effect and thermal stratification as it passes over a vertically inclined temperature-varying flat plate. The governing equations are transformed into a dimensionless form by applying the appropriate transformation and solved by using CrankNicolson method, numerically. The graphical results have been achieved using Mathematica. The results demonstrate that radiation and heat absorption have a significant effect on the velocity and temperature profiles on thermally stratified fluid.
