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 pipeWhen 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, highspeed camera was used to get the photography of oilinwater flow pattern, track bubble and drip, and measure the flow velocity and flow fieldAt the same time the velocity was compared with the one obtained by using the crosscorrelation 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 crosscorrelation methodIt can be used in the measurement of flow velocity and flow field of oil-air-water three-phase flow.

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。
