Variational Iteration Method for Solving Nonlinear WBK Equations
نویسنده
چکیده
In this letter, He’s Variational iteration method (VIM) is implemented for solving the nonlinear Whitham-Broer-Kaup partial differential equations. This method is based on Lagrange multipliers for identification of optimal values of parameters in a functional. Using this method creates a sequence which tends to the exact solution of the problem. The results are compared with those obtained by the Adomian decomposition method. The work confirms that the V IM method is superior and very faster to the ADM .
