Variational iteration method for solving Burgerʹs and coupled Burgerʹs equations

By means of variational iteration method the solutions of Burgerʹs equation and coupled Burgerʹs equations are exactly obtained, comparison with the Adomian decomposition method is made, showing that the former is more effective than the later. In this paper, Heʹs variational iteration method is introduced to overcome the difficulty arising in calculating Adomian polynomials.
