An analysis is carried out to study the flow and heat transfer characteristics
of a non-Newtonian power-law fluid over a stretching surface in the presence of
radiation and slip condition at the surface. The local similarity solution is used to
transform the system of partial differential equations, describing the problem, into
a system of highly coupled non-linear ordinary differential equations. The transformed
system of equations is solved numerically using the fourth order Runge-
Kutta method coupled with the shooting technique. The effects of the radiation
parameter and the slip parameter on both the flow and the heat transfer are investigated
and discussed. Also, it is found that the local skin-friction coefficient
decreases as the slip parameter increases. However, it is found that increasing
the slip parameter or the radiation parameter has the effect of decreasing the local
Nusselt number.
