摘　　要：饱和器是HAT循环中的关键部件 ,如何测量其内部水滴粒径、浓度及其变化是现在研究工作中的一个难题。文中描述了一种新型光学喷雾粒径、浓度测量系统 ,利用该系统对双流体喷嘴在空气中喷雾时水滴粒径及在不同位置的变化进行了测量 ,同时在相应位置和相同工况下用PDA对喷雾特性进行了比较测量。对得到的实验数据进行定量分析 ,说明测量结果的准确性。实验测量结果表明 ,用该系统测量喷嘴喷雾粒径是可行的 ,可以进一步用于饱和器内部水滴的测量。To measure the water droplet diameter and concentration as well as their variation in a humidifier, the key element of a humid air turbine (HAT) cycle, has long been an intractable problem during relevant experimental tests. In view of this the authors have developed an innovative mist-spray optical system for measuring the water droplet diameter and its changes at various locations during the mist-spray process of a dual-fluid nozzle in air. Meanwhile, at proper locations and under identical operating conditions a contrast measurement of mist-spray characteristics was conducted with the use of a phase Doppler anemometer. The measurement results indicate that the recommended system can be used for measuring nozzle mist-spray particle diameter and is well suited for the measurement of water droplet parameters in a humidifier.
