Study on interfacial tension, composition, density, viscosity and saturation of gas pha - se and liquid phase front in the slim tube under various injection pressures and injection rate.

分别研究了不同注入压力和注入气量下，细管中注气混相驱前缘和过渡带中气液两相的界面张力、组成、密度、粘度及饱和度的变化情况。

To separate the liquid and gas phase, the separator makes use of the difference in density between them, and takes advantage of ESP high speed rotating, which used to power a separating device.

液气分离器就是充分利用电泵机组的高转速、气体和液体之间悬殊的密度差异进行液气离心分离。

Then the corresponding sonic velocity of the two-phase flow is determined by the void ratio, pressure and density of the liquid phase.

其对应的音速与汽液两相流体的空泡率、压力及液相密度等因素有关。
