| 摘 要： | 基于电容层析成像技术和文丘里管流量计,提出改进的de Leeuw关系式来实现油气两相流质量流量测量.实际测量中应用电容层析成像技术获取两相流空隙率和流型信息,由获取的空隙率通过关联Lockhart-Martinelli参数得到质量流量含气率.该改进关系式根据不同的流型信息选择经验参数 (该参数与气相弗劳德准数有关),结合质量流量含气率及文丘里管流量计获取的差压信息实现两相流质量流量测量.油气两相流的实验结果表明所提出的改进de Leeuw关系式是有效的.

| Abstract: | Based on the electrical capacitance tomography (ECT) technique and Venturi meter,a modified de Leeuw correlation was presented for the mass flowrate measurement of oil-gas two-phase flow. According to the modified correlation presented,during the measuring process,the void fraction and flow pattern of the two-phase flow are obtained by using ECT technique; the gas content ratio of the mass flowrate is gained by associating the void fraction with Lockhart-Martinelli parameter; and the empirical parameter n,w... |
