We generalize the explicit high-order positivity-preserving entropy-stable spectral collocation schemes developed in [30, 34] for the three-dimensional (3D) compressible Navier Stokes equations to a time implicit formulation. The time derivative …
This paper presents a rigorous extension of the explicit, high-order, positivity-preserving, and entropy-stable spectral collocation schemes developed in Upperman 2023 and Yamaleev 2023 for the 3D compressible Navier-Stokes equations to a …
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 …
