Raeisi Faculty of Sciences, Mazandaran University, Iran Iran, Islamic Republic of Department of Mathematics Journal Article 2011 06 22 A. Noor et al. [7] analyze a technique by combining the variational iteration method and the homotopy perturbation method which is called the variational homotopy perturbation method (VHPM) for solving higher dimensional initial boundary value problems. In this paper, we consider the VHPM to obtain exact solution to Gas Dynamics equation.
