摘要
Main focus of present article is to discuss viscous fluid flow over a stretchable plate. The fluid saturates porous medium. Further, the magnetic field, thermal radiation, Joule heating and viscous dissipation impacts are accounted. Entropy generation is evaluated. Obtained PDE's system of the considered problem is converted to non-dimensional form by suitable variables. PDE's system (dimensionless) is tackled by a numerical scheme known as finite difference technique. The outcomes of entropy, velocity, skin friction, temperature and Bejan and Nusselt numbers through variation of influential variables are analyzed. The obtained output shows that velocity enhances with injection parameter and Reynolds number; however, it decreases with porosity and Hartmann number. Temperature increases through Eckert, Reynolds and Hartmann numbers. Entropy boosts with Reynolds, Hartmann and Prandtl numbers.
