This article presents the results of three-dimensional mathematical modeling of impingement with flat obstacle of two and four supersonic jets exhusting from conical nozzles into a highly rarefied medium. The simulation was performed using a modified OpenFOAM-Extended solver, where the method of S. K. Godunov is implemented. From the simulation results it was found that an increase in the number of jets leads to a significant change in the shock-wave structure of multiple jets, force on the bottom region and peripheral flow.
