Abstract
This paper analyses the effect of thermal radiation on a two-dimensional stagnation-point flow of an in-compressible magneto-hydrodynamic Carreau fluid toward a shrinking surface in the presence of convective boundary condition. Using the similarity transformations, the governing equations have been transformed into a system of ordinary differential equations. The resultant differential equations are solved numerically, by using bvp4c MATLAB solver. The behavior of the velocity and temperature as well as the skin-friction coefficient and the local Nusselt number for different values of the governing parameters, namely, magnetic parameter, power law index parameter, suction/blowing parameter, radiation parameter and convective parameter are discussed in detail.
