2D Numerical Simulation of Jet Injection into a Channel with a Cavity
Flow configurations with jet/supersonic flow interactions are met in different applications. Among them are supersonic aircraft cooling systems, thrust vector control devices, combustion chambers of hypersonic vehicles (scramjets), etc. From physical standpoint, the resulting flow structure represents complex phenomenon with separated, recompression and jet induced bow shocks, contact discontinuities and recirculating zones included. The jet itself possesses complex underexpanded structure, comprising barrel shocks and Mach disks. Thus, simulation of these types of flows is challenging task for numerical approaches, because accurate prediction of every flow detail has to be provided.
