We extend the explicit high-order positivity-preserving entropy stable spectral collocation schemes developed in [J. Upperman & N. K. Yamaleev, J. Sci. Comp., Vols. 94(1) and 95(1), 2023] for the 3-D compressible Navier-Stokes equations to a …

For turbulent flows in porous media, it is often assumed that the irregularity of the matrix would not affect the macroscopic, double-averaged (in time and space), parameters of turbulence. Hence, to improve currently used modelling techniques, the …

Nonlinear (entropy) stability analysis is used to derive entropy–stable no–slip wall boundary conditions at the continuous and semi–discrete levels for the Eulerian model proposed by Svärd in 2018 (Physica A: Statistical Mechanics and its …
