非线性振动下水平通道气液两相流动
|
摘要
将振动装置与气液两相流实验回路相结合,对非线性振动工况下水平通道内气液两相流进行实验研究。重点考察了不同振动参数对流型转换界限及摩擦压降的影响。流型图表明,非线性振动工况和稳态工况下的气液两相流动形式不同,提高振动的频率和幅度会导致流型转换界限发生改变。由实验得到的气液界面分布结果表明,振动频率对相界面波动程度有显著影响,而振动幅度则主要影响截面含气率。最后对比了非线性振动工况下的摩擦压降和经验公式的计算结果,发现两者在数值和分布上均无明显差异,说明稳态下两相流摩擦压降计算公式同样适用于非线性振动工况。
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.
