摘　　要：HAT循环关键部件增湿饱和器内是典型的气液两相流动,而液相水滴在饱和器内的平均粒径、平均速度和平均温度分布对饱和器内的传热和传质增湿起很重要作用。利用相位多普勒分析仪DualPDA(Phase Doppler Ana-lyzer)对冷态饱和器内流场的液相进行了大量详细的实验研究,同时利用基于虚拟仪器技术(VI)开发的程序和热电偶测量了炮和器内流场液相的温度分布。There is typical air-liquid two-phase flow in the saturator of HAT cycle. The distributions of mean diameters, mean velocities and mean temperature of liquid phase droplets are highly important for the heat transfer and mass transfer in the saturator. DualPDA (Phase Doppler Analyzer) is applied to study in detail the liquid phase of the flow field in the saturator at the cold state. And the distribution of temperature of the liquid phase of the flow field in saturator is measured used the program based on the technology of vinual instrument and thermometer.
