6) critical pressure ratio 压比临界点 1. In the study of flow oscillation and discrete frequency noise of impinging jet, it is found that there is a critical pressure ratio for a given nozzle and a nozzle-to-plate distance. 发现对于给定的喷嘴和冲击距离 ,存在一个压比临界点 ,当压比...
Based on the experimental results of previous investigators, credible assumptions are made to approximate these interphase processes which lead to a transcendental expression for the critical pressure ratio as a function of the stagnation pressure and quality. A solution to this expression also yields a...
The critical pressure ratio for choking is insensitive to Re, for which the averaged value is about 0.36. The time length required for the silicon nozzle to reach thermal equilibrium with sonic flow is about 10 minutes. The maximum deviation of discharge coefficients obtained at five different ...
