Casson fluid flow and heat transfer over an unsteady porous stretching surface

Abstract

The unsteady two-dimensional flow of a non-Newtonian fluid over a stretching porous surface having a prescribed surface temperature is investigated. Similarity transformations are employed to transform the governing partial differential equations into ordinary differential equations. The velocity and the temperature have been analyzed for different variations of the governing parameters Casson parameter, heat source parameter, Hartmann number, and Prandtl number are analyzed and discussed in detail. It was found that heat source and magnetic field modify the flow patterns and increase the temperature of the fluid.
