Because of the complexity and difficulty by theoretical study, solid-liquid two-phase flows are mainly studied by experimental method.
由于管道内部是复杂的两相流动,理论研究比较困难,历来的研究主要基于实验方法。
In this model, the characteristics of pseudo-homogeneous solid-liquid two-phase flows have been considered in the expression of wave propagation speed and also during treating with flow resistance.
