Comparative analysis of the accuracy of OPENFOAM solvers for the oblique shock wave problem

The article is devoted to a comparative assessment of the accuracy for solvers of the OpenFOAM open software package. As a test problem, we consider the classical twodimensional problem of a supersonic inviscid compressible flow falling on a flat plate at an angle of attack. As a result, an oblique shock wave is formed before the start of the plate. The simulation results for the solvers considered in comparison are compared with the known exact solution. Calculations for all solvers participating in the comparison were carried out with the same setting of the parameters of the incident flow and angle of attack. Special attention was paid to QGDFoam solver, which has controlled dissipative properties. For this solver, within the framework of a general comparison, calculations were carried out with a variation of the parameter that allows controlling dissipative properties. The results of estimates of deviations from the exact solution in various norms for all solvers are given.
