Flow and Heat Transfer of Power Law Fluid Film on an Unsteady Stretching Surface with Temperature Dependent Viscosity and Thermal Conductivity
نویسنده
چکیده
This paper considers the flow and heat transfer in a non-Newtonian power-law liquid film over a horizontal unsteady stretching sheet. The fluid viscosity and thermal conductivity are assumed to vary with temperature, whereas the Prandtl number is assumed to be constant. The transformed time dependent conservation laws are solved numerically. The velocity, temperature and thickness of the film, heat transfer and the friction at the sheet are found to be significantly affected with the variation of the fluid properties.
