    摘要
  • 摘要: 开展微重力膜式水气分离性能仿真研究，对水气分离技术设计与优化具有重要意义。针对微重力入口边界气液界面多尺度问题（入口流型问题）提出了基于界面概率近似方法的欧拉双流体模型，采用动量源项法解决几何多尺度问题（分离膜边界问题），为仿真研究提供了有效的入口及渗透边界。研究了典型工作参数下流道弯曲度对膜分离性能的影响，并从流动形态和作用力贡献2个方面分析了影响机理。结果表明：膜分离性能随流道弯曲度增大而降低，影响程度与入口含气率相关；直流道适于选作膜式静态水气分离器主要流道形式。

     

    Abstract: The simulation research on the performance of microgravity membrane gas-liquid separation is of great significance for the design and optimization of gas-liquid separation technology. The Eulerian two-fluid model with an interface probability approximation method is introduced for the computability of multi-scale gas-liquid interface problem at inlet boundary in microgravity (inlet flow pattern problem), and the momentum source method is proposed for multi-scale geometric problem at membrane boundary. The model and the method provide a valid entry and permeable boundary for the simulation study. The influence of channel curvature on the membrane separation performance with typical operating parameters is studied, and the influence mechanism is analyzed in the view of flow morphologies and force contributions. The results show that the membrane separation performance reduces with channel curvature increasing, and the influence is related to inlet gas phase volume fraction; straight channel is suitable for membrane static gas-liquid separator.
