Zusammenfassung:This paper presents a method for reconstructing the gas-dynamic parameters of gas flow based on non-contact PIV measurements of the velocity field. The wake flow past a model single rocket nozzle of an emergency escape system in the normal transonic (Mach number is 0.85) flight regime of the manned spacecraft rocket is considered. The flow around the nozzle is numerically simulated using the RANS and LES methods. The results obtained by the proposed reconstruction method are compared with numerical and experimental data.
