The unsteady film flow and heat transfer of a Cu-water nanofluid over a flat sheet caused by time-dependent stretching velocity and wall temperature distributions are studied. With the homogenous nanofluid model, the boundary layer equations are reduced to a set of ordinary differential equations with an unknown constant by means of similarity variables. The homotopy analysis method (HAM) is then introduced to give exact solutions. Besides, the effects of φ on the dimensionless thickness β, the velocity and temperature profiles are considered. It is found that the nanofluids can improve heat transfer characteristics to a large extent.
