Numerical Studies of Multi-fluid Systems

这项研究涉及两相流动的数值模拟，以深入了解相间相互作用的细节。这两个相是液体和气体，特别是气泡与周围液体之间的相互作用，气泡之间的相互作用，以及气泡与边界壁之间的相互作用。该技术将在控制偏微分方程组的三维中进行全面的数值模拟，并结合特殊的技术来跟踪和模拟界面配置。这项研究将提供关于多相流基本机理的基本信息，这是对各种工程系统中常见的此类流动进行建模所必需的。

This research involves numerical simulation of two-phase flows, in order to gain insight into the details of the interaction between phases. The two phases are liquid and gas, in particular the interaction between bubbles and the surrounding liquid, the interaction between bubbles, and the interaction between bubbles and bounding walls. The technique will be full numerical simulation in three-dimensions of the governing partial differential equations, combined the with special techniques to track and model interface configurations. The investigation will provide essential information on fundamental mechanisms in multi-phase flows, which is necessary for modeling of such flows as commonly encountered in various engineering systems.
