摘要:: 油气集输管道内气液两相流尤其是环状流在弯管处流动特性复杂，极易加剧管道腐蚀和破坏。为此，开展

90°水平弯管环状流实验，分析表观气速20～35 m/s，表观液速0.20～0.35 m/s 范围内的相分布、液膜流速及压力

变化规律。进而通过数值模拟研究水平弯管处相分布、压力分布和流速分布特征，对弯管处环状流流动特性规律

进行验证。结果表明：弯管底部和外侧液膜厚于弯管顶部和内侧，越靠近弯管中心，内外侧差异越大；表观气速增

加和液速降低使液膜分布趋于均匀；弯管内侧压力低于弯管外侧；受二次流动影响在低气速下弯管中心截面位置

最大压力较入口处增加。研究成果可为弯管冲蚀机理研究、弯管设计与保护提供理论基础。（图11，表1，参29）
