riser pressure

Static pressure distribution and relationship of gas holdup and liquid circulation velocity in reactor riser, downcomer and local zones are obtained by simulation.

通过模拟计算获得了反应器升、降流区及局部区域的静压分布、气含率和液体循环速度的变化规律。

The results showed that the pressure gradient in the riser and standpipe was gradually decreased with the superficial gas velocity, while it was increased with the circulating rate at the constant superficial gas velocity.

在提升管内表观气速一定的情况下随着循环量Gs的增加，提升管及立管内的压力分布也随之增大；

An experimental investigation on severe slugging in pipeline-riser systems was conducted at Multiphase Flow Lab in China University of Petroleum ( East China), in order to study the fluctuation characteristics of pressure and liquid holdup for severe slugging.

利用中国石油大学（华东）自主设计的试验装置，对严重段塞流的压力及持液率波动特性进行了初步研究。
