摘要: 对波纹管的气液两相流进行了数值模拟,分析了波纹管对分层流的流动调节作用,验证了数值模型的准确性,通过弯曲中心角、弯曲半径和管道内径比、弯管数目的敏感性分析,对波纹管的结构参数进行优化。结果表明,波纹管能够将分层流调节为非分层流,流动调节效果显著;弯曲中心角增大,流动调节作用增强,弯曲中心角的合理范围为90°~130°,取90°或120°便于加工建议采用;增加弯曲半径或者减小弯管内径,能够增加弯曲半径和管道内径比,增强流动调节作用,弯曲半径增加,波纹管尺寸增大,投资升高,建议采用减小弯管内径的方法;随着弯管数目的增加,波纹管的流动调节效果增强,应综合考虑安装空间、投资成本,适当选取弯管数目。

Abstract: This paper simulates the gas-liquid multi-phase flow in the wavy pipes. The effects of the wavy pipe on the laminar flow behavior and the accuracy of the numerical model are investigated. The effects of the bend angle, the ratio of the bend radius to pipe diameter and the number of bends on the flow behavior are analyzed. The geometry parameters of wavy pipes are optimized. The results show that the wavy pipe is effective in regulating the flow pattern and in mitigating severe slugging. The larger the bend angle, the more effective regulation of the flow pattern. The reasonable range of the bend angle is 90°~130° and when the bend angle is 90° or 120°, the wavy pipe is easier to process. Increasing the bend radius and reducing the internal diameter of the tube can increase the ratio of the bend radius to pipe diameter and enhance the regulation effect. With consideration of the investment, reducing pipe diameter is more suitable. With the increase of the number of bends, the wavy pipe regulates the flow pattern more effectively. The number of bends should be determined according to installation space and investment.
