摘要
在建立变截面通道内超音速汽液两相流升压装置的极限升压能力计算模型的基础上,对极限升压能力的影响因素进行了分析,定量计算了各影响因素对极限升压能力的影响,计算结果表明:极限升压能力随混合腔进出口截面积比增大而增大;随蒸汽压力升高而下降;随引流系数变化存在最小值;随进口低压水温的升高略有升高。这些对变截面通道内超音速汽液两相流升压装置的设计和应用具有重要意义。
Based on establishing the mathematical model for calculation the maximum lifting pressure performance (MLPP) of supersonic steam-water two-phase flow in channel of variable section, the key factors influencing MLPP are analyzed and calculated, the calculation results show that MLPP increases with the sectional area ratio of the mixture chamber and inlet water temperature, but decreases with steam pressure. These results could be beneficial to the application of supersonic steam-water two-phase flow in channel of variable section.
