【摘要】 对摇摆状态下水平管内气-水两相流流型进行了实验研究。实验发现,摇摆状态下两相流的压差波动有明显的周期性。本文根据各流型压差波动的差异判断摇摆状态下水平管内气-水两相流的流型。结果表明:通过与可视化观察和高速摄影观察的流型相比,利用压差特性曲线可以很好地判断摇摆状态下气-水两相流的流动型式。更多还原

【Abstract】 An experimental study on the flow patterns of gas-water flow was carried out in horizontal tubes under rolling state. It was found that the pressure drop of two phase flow was with an obvious periodi-cal characteristic. The flow pattern of the gas-water flow was distinguished according to the characteristics of the pressure drop in this paper. It was proved that the characteristics of the pressure drop can distinguish the flow pattern of gas-water flow correctly through comparing with the result of careful observation and high speed digital camera.更多还原
