摘要
近期进行的旋流塔板基础研究工作：测定塔板上两相流场及液滴粒径分布等亚微观参数，找出它们的变化规律；提出液滴运动的三维抛射模型和塔板效率模型，其计算结果与实验值及工业塔数据能较好地符合。
The recent fundamental research of rotating stream tray(RST )is introduced briefly in this paper. Two-phase flow field and droplet size distribution are measured and analysed above φ300mm RST,and the modelsof a three-dimensional droplet projectory trajectory and of a tray efficiency are provided.The simulated resultsof the tray efficiency agree well with the experimental and industrial data.
