Three-Phase Flow Measurements Using a Hot-Film Anemometer
Hot-film probes have been extensively used for local velocity measurements in single-phase liquid flows. In addition, they have been widely used for the measurement of the local volume fraction and phasic velocities in gas/liquid two-phase flows. In contrast, very few researchers have tried to use hot film probes for two-phase liquid/liquid and three-phase gas/liquid/liquid measurements; in particular, for the oil/water/gas flows which are of interest in the petroleum recovery industry.
This paper presents measurements of three-phase air/oil/water flows using a hotfilm anemometer. It will be shown that accurate measurements are possible using this technique.
