Abstract: Approximate solution of a class of boundary layer equations arising in dilatant non-Newtonian fluids is obtained by using Adomian decomposition method and Mathematica symbols calculation software. Approximation of the skin friction and the distribution curve of solutions are given for different parameters. The reliability and efficiency of the approximate solution are verified using numerical solutions.
