HIGH-ORDER ACCURATE EMBEDDED-BOUNDARY DISCONTINUOUS GALERKIN METHODS FOR INVISCID GAS DYNAMICS
V. Gulizzi, University of Palermo, Italy
This work presents a computational framework for solving the equations of inviscid gas dynamics over embedded geometries based on the Runge-Kutta discontinuous Galerkin method. The novelty of the proposed scheme is the ability to control the spurious oscillations that are typical of high-order schemes for non-linear hyperbolic PDEs by the use of suitably-defined damping terms.
