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.
