1管道油流携水系统的界面分布显示文摘成品油管道低洼处积水引起的腐蚀产物堵塞管道事故严重威胁管道的正常运行,为研究管道中油流携水作用机制,从试验、理论两个角度对油流携水系统的特性进行研究。以柴油和水为介质,在内径27 mm的水平-上倾管流试验系统上对上倾管段0.5 m位置处的出水量以及临界油相流量(出水量不为零时的最小油相流量)进行测量,同时根据试验模型,基于油水两相动量方程和光滑分层流稳定的条件,建立水相厚度梯度的计算模型,对水平测试段中相界面分布进行分析,对出水量以及临界油相流量进行预测。结果表明:新模型能很好地预测两参数的变化;在油流携水系统中,油相处于层流状态时,建立的水相厚度梯度模型能很好地预测相界面分布。徐广丽 张国忠 BRAUNER N ULLMANN A 刘刚 张鑫 2011中国石油大学学报(自然科学版)2011,35,1:7
