查询词典 let off steam

The calculation and experiment results show that the maximum lifting pressure performance decreases with the increase in throat diameter of channel of variable section, water flux of low pressure and pressure ratio of steam nozzle, and has its minimum value with water nozzle annular space. The coefficient of maximum lifting pressure performance may be as high as 26. In the design of steam injector, the larger pressure ratio of steam nozzle and the smaller water nozzle annular space are selected, the higher lifting pressure performance could be obtained.
