摘要
天然气绕三角翼产生旋流,使天然气中的游离水滴甩出,附着在管道内壁上,在气流的牵引下沿管道内壁向下游流动,实现了气水分离的目的。通过水洞实验,利用染色液流动显示技术,探讨了流体绕三角翼后产生旋流的可行性。同时,基于均匀设计思想对三角翼的前缘后掠角、后缘后掠角和迎角等几何参数分别做了5个水平的实验研究,均证实了天然气绕三角翼后产生旋流的可靠性,为该技术的应用奠定了基础。
Natural gas around the delta-wing generates swirl flow,so that free water droplets in natural gas are thrown off,attached to the pipe inner wall,pulled by the air to go downstream along the pipeline inner wall,then achieved the separation of gas-water.Through water tunnel experiment,staining flow visualization techniques are used to explore the feasibility of fluid around the delta-wing to result in cyclone.At the same time,based on uniform design ideas,for leading edge sweep angle of delta wing,trailing edge sweep angle,attack angle and other geometric parameters,five levels of experimental research are done.It confirms the reliability of gas swirling around the delta-wing resulting in cyclone,and lays the foundation for the realization of the technology.
