A Simple Modification of Homotopy Perturbation Method for the Solution of Blasius Equation in Semi-Infinite Domains

الملخص EN

A simple modification of the homotopy perturbation method is proposed for the solution of the Blasius equation with two different boundary conditions.

Padé approximate is used to deal with the boundary condition at infinity.

The results obtained from the analytical method are compared to Howarth’s numerical solution and fifth order Runge-Kutta Fehlberg method indicating a very good agreement.

The proposed method is a simple and reliable modification of homotopy perturbation method, which does not require the existence of a small parameter, linearization of the equation, or computation of Adomian’s polynomials.
