Abstract: In the recent paper, the modified Adomian decomposition method (ADM) with shooting method is applied to solve the Sakiadis flow problem. Traditionally, Sakiadis flow problem is solved numerically. However, a numerical solution could not easily differentiate and integrate because the data is discrete. In order to improve the problem, firstly, the analytic solution for the Sakiadis flow problem must be not discrete, so that the governing equations of Sakiadis flow could be differentiable and integrated. Hence, in this paper, the analytic solution can be obtained by using modified ADM with shooting method. Secondly, standard ADM only can get small interval, the analytic solution will diverge rapidly for a larger interval. The present method uses Modified Laplace ADM to converge the solution of the Sakiadis flow in the large interval. So this method is reliable and efficient in obtaining the analytic solution solutions that match well with those from the Runge-Kutta method, which is considered close to the exact solution. Finally, the entropy generation of the Sakiadis flow with radiation effect has been studied. The distribution of the entropy generation is discussed by discussing some parameters. For example, Pr, N_R, N_sh, N_sf, N_sx, Be number.
