本文对两相流中的空泡波现象进行了详细的线性和非线性分析。一种最先进的一维双流体模型被用作这一分析的基础。结果表明，相滑移对空泡波的频散有很大影响。特别是，滑移越小，出现的弥散越多。还发现可能会出现诸如激波和孤子之类的非线性波形。此外，虚拟质量力是空泡波模拟中的一个重要参数。结果表明，空泡波分析是评估双流体模型中闭合假设的一种很好的方法。它还暗示，为此目的需要仔细采集的空泡波数据。
This paper presents a detailed linear and nonlinear analysis of void wave phenomena in two-phase flow. A state-of-the-art, one-dimensional two-fluid model was used as the basis for this analysis. It is shown that void wave dispersion is strongly influenced by phasic slip. In particular, the smaller the slip the more dispersion occurs. It has also been found that nonlinear wave forms, such as shocks and solitons, may occur. Moreover, the virtual mass force was found to be an important parameter in the modeling of void waves. It is shown that void wave analysis is an excellent means of assessing the closure assumptions used in two-fluid models. It is also implied that carefully taken void wave data are needed for this purpose.
