摘要
本文针对超音速汽液两相流在变截面通道中的升压过程进行了实验研究,得到了变截面混合腔中超音速汽液两相流的压力变化规律,通过实验结果的分析得出了变截面混合腔中的渐缩部分的压力分布与出口压力无关、变截面通道的渐扩部分为一个单相流体扩压管、压力突变发生在变截面混合腔喉部和随着出口压力升高而激波强度增大、变截面超音速汽液两相流升压技术具有定流量特征等结论。
The process of supersonic steam-water two-phase flow in channel of variable section is studied experimentally and the pressure characteristics in channel of variable section are obtained. The experimental results show that the pressures of supersonic steam-water two-phase flow in the converging chamber have nothing to do with the outlet pressure, it is a single flow of water in the diverging chamber, the shock wave appears at the nozzle throat and increases with the outlet pressure, and the outlet flux of supersonic steam-water two-phase flow in channel of variable section hasn't been affected by the outlet water pressure.
