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,…
Formulation of entropy-conservative discretizations for compressible flows of thermally perfect gases
Alessandro Aiello, Carlo De Michele, Gennaro Coppola
This study proposes a novel spatial discretization procedure for the compressible Euler equations that guarantees entropy conservation at a discrete level for thermally perfect gas…
Impact of Structure-Preserving Discretizations on Compressible Wall-Bounded Turbulence of Thermally Perfect Gases
Alessandro Aiello, Andrea Palumbo, Carlo De Michele +1
Direct numerical simulations of compressible turbulent channel flow at supersonic and hypersonic Mach numbers are performed using a thermally perfect gas model for CO. The obje…
Entropy conservative discretization of compressible Euler equations with an arbitrary equation of state
Alessandro Aiello, Carlo De Michele, Gennaro Coppola
This study proposes a novel spatial discretization procedure for the compressible Euler equations which guarantees entropy conservation at a discrete level when an arbitrary equati…
