Entropy-stable fluxes for high-order Discontinuous Galerkin simulations of high-enthalpy flows

Kurzfassung

Accurate simulations of high-enthalpy reacting multi-species flows are a crucial component of the research and development cycle for design of new spacecraft. As available computing power increases, so does the range of physical phenomena that can be modelled. At the same time, development of new numerical methods that are able to fully leverage modern computing architectures is a crucial part of CFD development. Discontinuous Galerkin (DG) methods possess many properties that make them the preferred approach for future CFD solver development: 1) higher-order solution representation 2) low numerical dissipation 3) less stringent requirements on grid-shock alignment 4) improved computational efficiency due to data locality.
