将CFX数值模拟软件应用于LYHC-Ⅰ型入口扩散器气-液两相流数值模拟。几何建模采用SolidWorks、ICEMCFD协同进行,两相流物理模型采用SST模型,计算得到了该结构内非稳态的三维流场、液相分布等特征参数的分布特性,研究结果可为该结构的进一步改进和优化设计提供参考依据。
CFX numerical simulation software was applied to numerical simulation of gas-liquid two-phase flow in LYHC-Ⅰ inlet diffuser. The geometrical modeling is carried out by SolidWorks and ICEMCFD. The SST model is adopted for the physical model of the two-phase flow, and the distribution characteristics of the unsteady three-dimensional flow field and liquid phase distribution in the structure are calculated. Further improve and optimize the design provide a reference.
