Shock Waves of Rarefaction in Computational Gas Dynamics
Abstract:
Properties of various gas dynamics difference schemes (conservative, nonconsevative and completely conservative) are investigated on the basis of a classical moving piston problem. Its shown that shock wave can appears in rarefaction wave solution for piston moving out of gas. Shocks appear when low stability schemes are used for these tasks. Explanation of this effect and possible ways of its elimination are proposed.
