The non-invasive measurements were conducted by using a high-speed motion analyzer.For the vertical slug flow, the coefficient C_1 was found to be very close to the ratio of themaximum velocity to the average velocity in the profile. For the inclined slug flow, the value ofC_1 is smaller than that for the vbertical case because the nose tip of the Taylor bubble usuallydeviates from the centerline. The drift velocity is increased with the decrease of inclinationangle. Based on the theoretical analysis and experimental data, the bubble velocity correlationswere obtained. The results are in good agreement with the available data.展开更多
