### Numerical simulation of the motion of a micropolar Casson fluid through a porous medium over a stretching surface

**ABSTRACT**

The present study examines the motion of a micropolar non-Newtonian Casson fluid through a porous medium over a stretching surface. The system is pervaded by an external uniform magnetic field. The heat transfer and heat generation are taken into consideration. The problem is modulated mathematically by a system of nonlinear partial differential equations which describe the equations of continuity, momentum and energy. Suitable similarity solutions are utilized to transform the system of equation to ordinary nonlinear differential equations. In accordance with the appropriate boundary conditions, are numerically solved by means of the finite difference technique. Also, the system is solved by using multistep differential transform method. The effects of the various physical parameters, of the problem at hand, are illustrated through a set of diagrams.
