Abstract: The boundary layer flow over a uniformly moving vertical surface with suction or injection is studied when the buoyancy forces assist or oppose the flow. Similarity solutions are obtained for the boundary layer equations subject to power law temperature and velocity boundary conditions. The effect is of various governing parameters, such as Prandtl number Pr, temperature exponent n, injection parameter d, and the mixed convection parameter lambda = Gr/Re2, which determine them velocity and temperature distributions and the heat transfer coefficient, are studied. The heat transfer coefficient increases as λ, assisting the flow for all d at Pr = 0.72 however, for n = -1 it decreases sharply with lambda. On the other hand, increasing λ has no effect on heat transfer coefficient for Pr = 10 at n = 0, and 1 for almost all values of d studied. However, for n = -1 it has similar effect as for Pr = 0.72. It is also found that Nusselt number increases as n increases for fixed lambda and d.
