摘　　要：目前泡沫流体流动规律尚未形成统一完整的理论体系,且经典的流型图对于泡沫流体流型判别的准确度较低。因此本文基于可视化实验平台,研究了水平管道泡沫流体流型。结果发现,在气体流量27.28~163.68 m^(3)/h、液体流量22.6~1356.4 L/h范围内,随着气体流量或液体流量的增加,泡沫流体流型逐渐由泡沫波浪流过渡到不完全环状波浪流,再到泡沫完全环状流。相同液体流量下气体流量增加时流型的转变趋势与相同气体流量下液体流量增加时的趋势一致。At the moment,the flow law of foam fluid has not yet developed a unified and complete theoretical framework,and the classic flow pattern diagram has a low accuracy in recognizing foam fluid flow patterns.Therefore,this paper firstly investigated the characteristics of foam fluid flow patterns in horizontal pipes using a self-designed visual experimental platform.The findings demonstrate that,within the range of gas flow rates of 27.28-163.68 m^(3)/h and liquid flow rates of 22.6~1356.4 L/h,the flow pattern of foam fluid gradually transition from foam wave flow to incomplete annular wave flow and then to complete annular flow.The trend of the change in flow pattern when the gas flow rate rises while the liquid flow rate stays the same is consistent with the trend when the liquid flow rate rises while the gas flow rate stays the same.
