Parametric Study of the Accuracy of OpenFOAM Solvers for the Oblique Shock Wave Problem

The article is devoted to a parametric study of the accuracy of four solvers of the OpenFOAM package. As a test problem, we consider the classical two-dimensional problem of the fall of a supersonic inviscid compressible flow onto a flat plate at an angle of attack. As a result, an oblique shock wave is formed before the start of the plate. The problem is considered when varying the defining parameters of the problem, such as the angle of incidence of the flow on the plate and the Mach number. As a result of the calculations, a solution was obtained for the class of problems, where this class is determined by the ranges of variation of the determining parameters. For all solvers in the class under consideration, deviation surfaces from the known exact solution are constructed. The resulting estimates can be useful for users and developers of solvers.
