Discontinuous Galerkin Method For Computational Aeroacoustics

Discontinuous Galerkin method is a time-discrete higher-order compact scheme and its solution is accurate. It is also automatic methodology to raise the solution accuracy to any level. One-dimensional (1-D) convection solution shows its excellent accuracy. The original multidimensional version is very expensive. An alternative is suggested in this summary by combining 1-D staggered with an implicit mesh arrangement. This alternative is also accurate and less expensive but more research is required to expand its application to complex geometry and three-dimensional (3-D) problems.
