The nonlinear equation from Prandtl has been solved by Blasius using Fourth order Runge-Kutta methods. The thesis aims to study the effect of solving the nonlinear equation using different numerical methods. Upon the study of the different numerical methods be use to solve the nonlinear equation, the Predictor-Corrector methods, the Shooting method and the Modified Predictor-Corrector method were used. The differences of the methods with the existing Blasius solution method were analyzed. The Modified Predictor-Corrector method was developed from the Predictor-Corrector method by adjusting the pattern of the equation. It shows the graphs of the f, f’ and f’’ against the eta. All the methods have the same shape of graph. The Shooting method is closely to the Blasius method but not stable at certain value. The Variational Iteration method that has been used cannot be proceeding because the method only valid for the earlier flows and lost the pattern at the higher value of eta. It can be comprehend that the Predictor-Corrector methods, the Shooting method and the Modified Predictor-Corrector method achieve the conditions and can be applied to solve the nonlinear equation with minimal differences. The methods are highly recommended to solve the Sakiadis problem instead of the stationary flat plate problem.
