Large-eddy simulation of a channel flow over an irregular porous matrix

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 …

Entropy Stable No-Slip Wall Boundary Conditions for the Eulerian Model for Viscous and Heat Conducting Compressible Flows

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 …
