This work will present a GPU-capable low-dissipation semi-implicit SEM algorithm suitable for performing scale-resolving simulations of wall-bounded, turbulent compressible flows, including at supersonic regimes. Such a model is motivated by issues encountered when performing LES and DNSs of typical aeronautical flows, where small element sizes, especially for the high-order types of elements used in SEM, imply that the maximum time-step size possible with an explicit method quickly becomes unfeasible even when using the latest in supercomputing hardware.
