金属板波填料板片上开孔孔型对气流径向混合的影响

Influnence of Hole Type of Mellapak on Radial Mixing of Gas Stream

在两相流工况下，对两种孔型板波填料作气流的径向分布性能的实验研究。提出用液气动量比来反映不同操作工况条件。对比结果表明，桥孔比圆孔更有利气流的径向扩散。

The radial mixing characteristics were studied for different types of hole in the Mellapak under two phase countercurent flow. The ratio of liquid to vapor momentum flux were used to describe various operating conditions. The results show that improved hole is more advantageous to the radial mixing of gas stream.
