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