چکیده

This paper examines the effects of thermocapillarity and thermal radiation on the boundary layer flow and heat transfer in a thin film on an unsteady stretching sheet with nonuniform heat source/ sink. The governing partial differential equations are converted into ordinary differential equations by a similarity transformation and then are solved by using the homotopy analysis method HAM . The effects of the radiation parameter, the thermocapillarity number, and the temperaturedependent parameter in this study are discussed and presented graphically via velocity and temperature profiles.
