In this paper the mathematical modeling of the interaction of a single supersonic jet with a flat obstacle in a rarefied atmosphere and Mach numbers at the nozzle exit 4 are considered. Mathematical modeling using free OpenFOAM-Extended software and authors' program are done. Comparison of calculation methods: PISO algorithm, Rusanov and Godunov schemes was carried out. The comparison results show a qualitative coincidence in the shape of the supersonic jet, wall jet and the system of shock waves. But the numerical results are quantitatively different, pressure on flat obstacle varied within 7-14 kPa. The peak of pressure is on the periphery for results of sonicFoam and dbnsFoam. For all solvers average pressure at axis of jet is 8 kPa and the first barrel of wall jet is started about at 0.4 meter from axis was obtained. |
