Abstract
This paper presents a numerical investigation on heat transfer in power-law fluids aligned with a semi-infinite plate in the presence of viscous dissipation and radiation. The effects of power-law viscosity on temperature field are taken into account by assuming that the thermal diffusivity varies as a function of velocity gradient. Since the problem is very complex to solve analytically, a similarity transformation based on the least square approximation principle and shooting technique may be a considerable approach. The effects of generalized Prandtl number, viscous dissipation and radiation on the heat transfer are tabulated.
