Abstract

The inspiration driving this article is to explore the unsteady MHD flow across stretching surface along with suction/injection and heat source/sink inserted into a porous medium. Governing PDEs are altered into non-linear ODEs, which are numerically solved by utilizing MATLAB built-in routine Bvp4c. Impact of physical parameters affecting velocity and energy are investigated using portrayal and tabular expressions. The results displayed that by improving the heat source and permeability parameter, temperature profiles increase while antipodal effect is observed in velocity profiles. The effect of various parameters like magnetic, suction/injection, Eckert and Prandtl number are also examined through graphs. The achieved results thus affirm that an exquisite agreement is acquired with those available in the open literature.
