Pressure-equilibrium-preserving and fully conservative discretization of compressible flow equations for real and thermally perfect gases
Gennaro Coppola, Alessandro Aiello, Carlo De Michele
Numerical simulations of compressible real-fluid flows are notoriously plagued by spurious pressure oscillations arising in regions of abrupt flow variations. As a possible remedy,…
