非线性振动下水平通道气液两相流动
Gas-liquid two-phase flow in horizontal channel under nonlinear vibration
摘要
Abstract
The vibrating device is combined with the gas-liquid two-phase flow experimental loop to carry out experimental research on the gas-liquid two-phase flow in the horizontal channel under nonlinear vibration conditions. The influences of various vibration parameters on flow regime transition line and frictional pressure drop were analyzed. The flow transition boundary diagrams illustrate that flow conditions under nonlinear vibration is different from that under steady state. The whole flow pattern has an outward expansion tendency with the slug flow as the center as vibration frequency or amplitude increases. Vibration frequency has a significant effect on fluctuation degree of gas-liquid interphase, whereas vibration amplitude mainly affects void fraction. There was no obvious difference on the values and distribution between the calculation deviations in fluid flow under nonlinear vibration and the calculation deviations in fluid flow under steady state by using different empirical formulas. The results show that the empirical correlations for frictional pressure drop of two-phase flow under steady state are also suitable for the calculation of frictional pressure drop of gas-liquid two-phase flow under nonlinear vibration.关键词
