Effects of non-linear radiation and reaction on stagnation point flow of carreau fluid in the presence of magnetic field

Abstract

In this study, mixed convection Magnetohydrodynamics stagnation point flow of Carreau fluid is considered. Flow is two-dimensional and passes through in porous medium. The effects of different physical parameter like, non-linear radiation, chemical reaction and heat generations is studied. The governing equations are transfer in to a system of ODE’s using the similarity transformation. The suitable HAM is applied for solution of dimensionless momentum, energy and concentration equations. For better understanding of the problems, the numerical values of skin friction, Nusselt number and Sherwood number is obtained and presented in table. From the graphical results, it is concluded that the motion of fluid improves with increasing the values of magnetic fields, mixed convection parameter and permeability of porous medium parameter. Motion of fluid reduces with rising value of local Weissenberg number. Mass transfer process tends to slow with increasing values of chemical reaction. It is also concluded that the heat transfer process increases with increasing the values of thermal ratio parameter, thermal radiation and heat generation parameter.
