新型垂直筛板(NWE　VST)阶跃浓变传质混合池模型的研究

Study of the Concentration Step Changing Mass Transfer Mixing Pool Model in New VST

作者通过对新型垂直筛板（ＮｅｗＶＳＴ）的研究发现，该类喷射工况下工作的塔板，板上液体运动的推动力包括板上液面梯度及塔内气体动能．在此基础上推导出了适用于ＮｅｗＶＳＴ的传质效率模型并进行了实验验证．

In spray regime,the motive force of the liquid moving on the trays consists of tow parts.One of them is the liquid surface gradient on the tray,another is the kinetic energy of the gas in column. The authors derived the tray effciency model in new vertical sieve tray(New VST)that works in spray regime,and examined it in experiments.
