气体穿过筛板上固液两相流层时的阻力特性

Resistance characteristics when gas goes through the solid liquid two phase flow layer on a tray.

对气体穿过筛板上固液两相流层的流动特性进行了研究，关联出了气体穿过筛板上固液两相流层时泡沫工况下的筛板压降公式，为工程应用提供实验基础。

The flow characteristics were studied when gas went through the solid liquid two phase flow layer on a tray,the pressure drop formula of sieve trays was derived when gas went through the solid liquid two phase flow layer on a sieve tray in a bubble condition,and experimental bases were given for engineering application.
