Comparative Analysis of the Accuracy of OpenFOAM Solvers in Simulating High-Velocity Flow Around a Double Wedge

This article is devoted to a comparative analysis of the accuracy of various solvers of the OpenFOAM software package in numerical modeling of supersonic inviscid gas flow past a double wedge. A two-dimensional steady-state problem of flow formation with the intersection of oblique shock waves is considered. A comparison of standard solvers is made rhoCentralFoam and sonicFoam , as well as third-party developments pisoCentralFoam and QGDFoam . The results obtained in tabular form are visualized as error surfaces. The analysis showed the best accuracy of solvers rhoCentralFoam and QGDFoam for both the density field and the velocity modulus field. The results obtained can be used both in fundamental research and in engineering calculations that require high reliability of complex flow modeling.
