Implicit BDF2 dual time-stepping positivity-preserving entropy-stable schemes for unsteady compressible viscous flows
Mohammed Sayyari, Nail K. Yamaleev
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…
Implicit dual time-stepping positivity-preserving entropy-stable schemes for the compressible Navier-Stokes equations
Mohammed Sayyari, Nail K. Yamaleev
We generalize the explicit high-order positivity-preserving entropy stable spectral collocation schemes developed in Upperman 2023 and Yamaleev 2023 for the three-dimensional (3D)…
Development and analysis of entropy stable no-slip wall boundary conditions for the Eulerian model for viscous and heat conducting compressible flows
Mohammed Sayyari, Matteo Parsani, Lisandro Dalcin
Nonlinear entropy stability analysis is used to derive entropy stable no-slip wall boundary conditions for the Eulerian model proposed by Svärd (Physica A: Statistical Mechanics an…
