New quasi-natural artificial viscosity models for compressible fluid flow, with an improved entropy production mechanism

Krzysztof Banaś, Leszek Demkowicz
The paper presents formulation of artificial viscosity models based on the principle of entropy production for viscous compressible flows. An application of the derived models implemented in an h adaptive finite element code to a benchmark ramp test problem is included as a practical test of their performance.
Keywords: artificial viscosity; compressible fluid flow; entropy production
