| 摘 要： | 利用实验数据对变截面通道内渐缩部分超音速汽液两相流压力随进水温度、进水流量和进出口水温升的变化规律进行了定量分析，得出了水喷嘴出口压力的计算方法和定量公式。以此为基础，建立了变截面通道内超音速汽液两相流升压性能的计算模型，该模型的计算结果与实验值的误差小于10％，而且具有一定的通用性研究结果对超音速汽液两相流升压技术的开发具有重要意义

| Abstract: | According to the experiment results of steam-water two-phase flow in variable channel (Steam Injector), the relationships among the outlet pressure of water nozzle and the inlet low-pressure water temperature, flow flux,or the water temperature rise are quantitatively studied. The mathematical formula for the outlet pressure of water nozzle is obtained. Then the pressure-lifting performance calculation model of supersonic steam-water two-phase flow in variable channel is developed. The error between the calculation result using this model and the experiment result is less than 10%. These are beneficial to the development of the lifting pressure technology with supersonic two-phase flow in channel of variable section. |
