摘要 对叶片泵内3种气液两相流动情形进行了介绍,并对比了叶片泵内气液两相流动与管内两相流动的不同. 从泵送气液两相流体的基础理论、试验及数值研究3个方面概括了气液两相流下泵内部流动研究现状:由于理论分析方法的局限性较大,采用解析数学模型描述两相流动不稳定现象仍存在困难;试验研究和构建数值模拟方法是推动气液两相流条件下泵内部流动理论研究的主要手段,目前试验方面多集中于性能试验及采用高速摄影技术对泵内气泡运动及流型变换进行研究,PIV、超声成像和射线衰减等新型可视化技术应用于泵内气液两相流动的研究还较少,且对气液两相条件下压力、振动、噪声等不稳定流场的流动诱导特性还鲜有研究;现有数值计算方法不仅能对气液两相流下泵的性能做出预测,还能对其内部流动特性进行分析,但在高含气率下计算的精度不高,需要在试验的基础上对现有湍流模型和多相流模型进行修正以满足研究的需要.
