| Abstract: | Various grids density are used to solve Euler Equation by using Beam-Warming's Finite difference method. Error estimates are obtained by using Richardson Extrapolation. The relation between grid density and artifical dissipation has been discussed and the accuracy of various soluations has been analysed . |
