Abstract

In this paper, viscous flow and heat transfer over an unsteady stretching surface is investigated with slip conditions. A system of non-linear partial differential equations is derived and transformed to ordinary differential equations with help of similarity transformations. Numerical computations are carried out for different values of the parameters involved and the analysis of the results obtained shows that the flow field is influenced appreciably by the unsteadiness, and the velocity slip parameter. With increasing values of the unsteadiness parameter, fluid velocity and the temperature are found to decrease in both the presence and absence of slip at the boundary. Fluid velocity decreases due to increasing values of the velocity slip parameter resulting in an increase in the temperature field. Skin-friction decreases with the velocity slip parameter whereas it increases with unsteadiness parameter. The rate of heat transfer decreases with the velocity slip parameter while increases with unsteadiness parameter. Same feature is also noticed for thermal slip parameter.
