Heat transfer over a stretching surface with variable surface heat flux

Heat transfer over a stretching surface with variable surface heat flux and uniform surface heat flux subject to injection and suction is examined. The boundary layer equations are transformed to ordinary differential equations, containing an injection parameter I, velocity exponent parameter M, heat flux exponent parameter lambda and Prandtl number P-r. The effect of these parameters is studied. Suction increases the heat transfer from the surface, whereas injection causes a decrease in the heat transfer.
