摘要
介绍了用热膜流速仪对精馏筛板上气液两相流的检测工作，讨论了适合于筛板上气液两相流测定的热膜流速仪检测信号的识别和标定方法，给出了筛板上两相流流场和气含率的测定结果。
It was presented of the measurement of the gas liquid two phase flow on sieve trays by using hot film anemometers,the identification and standardization of the measurement signals of the hot film anemometers suitable for gas liquid two phase flow on sieve trays were discussed,the measurement results of the flow fields and the ratio of air content on sieve trays were given.
