摘要
A numerical method for the simulation of separated cold gas nozzle flows is presented and applied to six subscale nozzles. The nozzles considered were a truncated ideal nozzle, two thrust-optimized parabolic nozzles, and three dual bell nozzles. For the thrust-optimized parabolic contours, the occurrence of free and restricted shock separation and the cap shock pattern are discussed. Comparisons with experimental data are provided. Shortcomings of the numerical method are pointed out.
