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.
