Examples
- Through the paper " s study , the cell - centred finite volume algorithm and the 2 - order ausm + finite volume algorithm can solve the subsonic flow problem well ; the nnd finite volume algorithm and 2 - order ausm + finite volume algorithm can solve the hypersonic flow problem well
研究表明，对于跨音速问题，格心以及二阶ausm +格式解决的很好；对于高超声速问题， nnd和ausm +格式解决的很好。 - The main results are : supersonic region and subsonic region can co - exist in flow path simultaneously , subsonic flow is insignificance for engine performance ; total pressure of primary rocket should be decreased when mach number is increased . in the experimental aspect , some components of ejectorjet experimental system were improved , ejectorjet experiments using alcohol as secondary fuel were conducted
由数值计算获得的结论为：引射火箭内的一般流态为超音速区与亚音速区共存，亚音速区不具备做功能力；飞行马赫数增大，引射火箭内更易于产生壅塞；为了获得最佳的性能，随着飞行马赫数的提高，应当降低一次火箭的工作压强。
