水平管内油水两相流流型的实验研究

利用白油和自来水作为实验介质，在内径为２６．１ｍｍ、长约３０ｍ的水平不锈钢多相流实验环道上进行了油水两相流实验。实验中进行了流型测量和观察，观察到了７种油水两相流型，分别属于分散、分离和分散分离混合流型。对油水两相流型及流型间的转化作了仔细的描述，根据流型特征进行了流型划分。

Experiment Investigation on Oil-water Two-phase Flow Pattern in Horizontal Pipe

Oil-water two-phase pipe flow experiment has been conducted on horizontal multiphase flow experiment loop,made of stainless steel pipe with 26. 1 inner-diameter and 30 m long,by using white oil and tap water as experimental medium. 7 different flow patterns have been found by detecting and watching flow pattern during the experiment process,which can fall into following 3 kinds :dispersed flow,stratified flow and semi-dispersed semi-stratified flow. Oil-water horizontal pipe flow pattern appearance and the transition between different flow patterns are depicted in detail. Also the oil-water pipe flow patterns are classified, according to their own different flow characteristic.
