“…An in-house code, AstroFoam, which was developed based on the OpenFoam platform, was used in the present study. AstroFoam has been used in the previous studies for simulating multicomponent supersonic flows and can capture shock waves and resolve turbulent eddies with high resolutions (Li et al, 2016a(Li et al, , 2016b. AstroForm adopts the second-order, semidiscrete, non-staggered, central-upwind, Kurganov and Tadmor (KT) scheme (Kurganov and Tadmor, 2000), which has been implemented in the OpenFoam framework (Greenshields et al, 2009) in order to capture the flow discontinuities (e.g., shock waves) with nonoscillatory and low-dissipation features.…”
