| Abstract: | The similarity solution equation of laminar boundary layer flow with suction/injection in power law fluid was studied in this paper.The corresponding approximate analytical solutions and skin friction coefficients were obtained for giving power law exponents by the Adomian analytical decomposition technique.Moreover,the reliability and efficiency of the approximate solution and the conclusions obtained from the approximate solution were verified using numerical solutions. |
