Comparison of Modern Methods for Shock Hydrodynamics
The accuracy and efficiency of several methods are compared for simulating multifluid compressible flows. The methods include a Godunov scheme (Colella, 1985), a Weighted Essentially Non-Oscillatory method (Jiang and Shu, 1996), an Arbitrary Lagrangian Eulerian algorithm (Marinak et al., 2001) and a compact scheme (Cook and Cabot, 2005). Test problems include a compressible breaking wave, the Shu-Osher problem, the Taylor-Green vortex and decaying turbulence. The compact method employs an artificial bulk viscosity for treating shocks and an artificial shear viscosity for modeling turbulence. The compact method is demonstrated to capture shocks as well as the other schemes, while providing superior resolution of post-shock features.
