A 2D Analysis of the Influence of Artificial Viscosity Terms on Solutions of the Euler Equations
KTH, Superseded Departments, Numerical Analysis and Computer Science, NADA.
1997 (English)In: Journal of Computational Physics, ISSN 0021-9991, E-ISSN 1090-2716, Vol. 138, no 1, 103-120 p.Article in journal (Refereed) Published
Abstract [en]

We analyze the influence of artificial viscosity on solutions of the Euler equations in the neighborhood of oblique shocks in 2D by studying a discrete, linear model equation. Based on the linear analysis an artificial viscosity model is derived. It is tested on two different test cases with the Euler equations: flow over a wedge and Mach-3 flow in a wind tunnel with a step.
