In gas-liquidflow, inertial effects cause the liquid to tend to lag behind the gas phase.
在气-液两相流动中，液相由于惯性其流动滞后于气相。

However, it is very difficult to design and scale up this kind of reactor, in that the present study has focused on the transient characteristics of the inherent gas-liquidflow increasingly.
The liquid in the pipeline under certain conditions and partially vaporizes into gas state, bubble, formation of gas-liquid two-phase flow which is the process of flash.
