Impact of channel curvature on microgravity membrane gas-liquid separation performance

  • 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。
