Multigrid solution for the Euler equations in axisymmetric flow
Abstract
A two-dimensional multigrid method for Euler equations is extended to a three-dimensional axisymmetric case. The basic features of the original method, such as finite volume form and flux vector splitting, are retained, and so too is the implicit time integration scheme with a multigrid algorithm. Several test cases are studied in various flow regimes, and the results are compared with references. The performance of the extended code is found to be fair, but the convergence is degraded compared to the original two-dimensional code.
