摘要

以35#润滑油、空气和自来水为实验介质，对垂直上升管内的油气水三相流的流场与流速进行了实验研究。在水流量为3.18 m 3·h -1、空气流量为0.25 m3·h -1、油流量为0.4 m3·h -1的工况下应用高速摄像机对水包油流型进行了拍摄，并跟踪气泡及油滴，对流速与流场进行了测定，同时与DPIV中的互相关法求出的流速进行了对比，实验结果表明，应用跟踪气泡及油滴的方法同DPIV的互相关法求出的流速与流场存在较小的误差，可以应用于油气水三相流中的流速与流场的测定。

Abstract

With 35# lubricating oil

air and water as the test media

a pilot study was performed on the flow velocity and the flow field of the oil-air-water three-phase in a vertical rise pipeWhen water flow rate was 3.18 m3·h-1

air flow rate was 0.25 m3·h-1

oil flow rate was 0.4 m3·h-1

highspeed camera was used to get the photography of oilinwater flow pattern

track bubble and drip

and measure the flow velocity and flow fieldAt the same time the velocity was compared with the one obtained by using the crosscorrelation method in digital particle image velocimetry technique (DPIV)The test results showed relatively small errors in the flow velocity and flow field determined by the tracking bubble and drip method and the crosscorrelation methodIt can be used in the measurement of flow velocity and flow field of oil-air-water three-phase flow.
