摘　　要：在变截面通道超音速汽液两相流升压装置的升压试验基础上 ,对升压装置混合腔阻力的影响因素进行了分析计算 ,得出了混合腔阻力与各影响因素的计算式。升压装置整体升压计算模型的计算结果与实验结果的相对误差小于 15 % 。Based on experimental study for boosting pressure performance of a supersonic steamwater twophase flow pressure booster with variable crosssection conduit, the key factors affecting the mixingchamber resistance of a pressure booster have been analysed and calculated, the calculating formula of mixingchamber resistance and every affecting factor being obtained, and the relative error between calculated result and experimental result being less than 15%. This can basically satisfy the requirements of industrial use.
