Other AbstractThe performance of oil-water two-phase flow in downward and upward vertical pipes is investigated by 0.28 m/s–4.65 m/s. In the research, pressure sensors, high speed camera and the quick closing valve system are used to measure the pressure drop, flow regimes and in-situ oil volume fraction respectively. The frictional pressure drop in flow is predicted by two-fluid model. The results show that, the generalized annular flow can decrease the frictional pressure drop greatly, and the frictional pressure drop should be divided into wall friction and interfacial friction which can be predicted by two-fluid model in the accuracy of 20%. Also, the quantitative description of velocity-slip is given that the oil phase velocity in downward and upward vertical pipes is greater than water and the difference becomes greatest in the oil volume fraction of 60%-80%. experiment. In the present study, a U-tube with the 25 mm inner diameter, 1 500 mm vertical length and two reductions from 50 mm inner diameter to 25 mm inner diameter are designed to obtain the generalized annular flow regime. And, the white oil is used as the oil phase (97 mPa·s, 860 kg/m3), the oil volume fraction is from 0 to 100% and the mixture velocity is in the range of
