Based on the flow mechanism and performance of gas liquid two phase plug flow in oil gas gathering line, a slug unit are divided into both gas slug region with liquid film and liquid slug region.
A more detailed multi fluid model was developed with the gas phase divided into several groups according to bubble size to describe bubbly flow in a vertical pipe.
根据气泡的尺寸划分气相,采用时间平均法建立了描述垂直管道内层流泡状流运动的多流体模型。

Based on the laws of motion of biphase dust-gasflow in a cyclone, improvement was made for its design so as to develop a new-type flow-divided cyclone.
