摘要
基于油/水两相流的漂流模型构造确定相分布系数和油泡直径指数的参数团,确定了基于最小二乘法的求解方法。为对解释方法进行验证,进行垂直小管径油/水两相流的动态实验。实验结果显示,解释的含水率与标定含水率符合很好,最大绝对误差为4.9。
Investigate the drift-flux modeling on oil/water two-phase flow.Construct parameter group to determine the phase distribution coefficient and oil bubble diameter index,and determine solving methods based on least squares.In order to verify the interpretation,do dynamic experimental on oil/water two-phase flow in vertical small diameter tubes.Experimental results show that interpretation of the water cut corresponds to known water cut well and maximum absolute error is 4.9.
