本文讨论了用单压单速两相模型和移动网格方法计算可压缩两相流问题。一个HLLC型计划的任意拉格朗日-欧拉制定的背景下，解决五方程模型。此外，扩展到多组分的情况下，也检查。该方法首先评估各种黎曼问题，包括固定和移动网格的应用程序，显示其简单性和鲁棒性。该方法还测试2-D移动网格应用程序，包括流体-结构相互作用。传热传质模型最后检查两相混合物。采用水击分步法和闪蒸快速降压法进行了计算。与现有的实验数据得到了很好的协议。所有计算均采用Europlex快速瞬态动力学软件进行。
Computation of compressible two-phase flows with single-pressure single-velocity two-phase models in conjunction with the moving grid approach is discussed in this paper. A HLLC-type scheme is presented and implemented in the context of Arbitrary Lagrangian–Eulerian formulation for solving the five-equation models. In addition, the extension to multicomponent cases is also examined. The method is first assessed on a variety of Riemann problems including both fixed and moving grids applications showing its simplicity and robustness. The method is also tested on 2-D moving mesh applications including fluid–structure interactions. The heat and mass transfer modeling is finally examined for two-phase mixtures. Computations using a fractional step approach of water hammer and fast depressurization with flashing are performed. Good agreement is obtained with available experimental data. All computations are performed with theEuroplexusfast transient dynamics software.
