摘要
螺旋管式蒸汽发生器由于其结构、换热性能等方面的优点在快堆和高温气冷堆中被广泛采用。本文在螺旋管束流动诱发振动实验研究的基础上，根据所获得的螺旋管束在横向气流冲刷下的实验数据，和美国阿贡实验室Ｓ．Ｓ．Ｃｈｅｎ在横向水流冲刷下的实验数据，建立了螺旋管束流体弹性不稳定的半经验模型和可供实际应用的设计准则。
In sodium cooled reactors and high temperature gas cooled reactors(HTR),helical coil steam generator has been extensively employed because of it's advantage in tight structure、good heat transfer and small size. Based on the experimental study for flow induced helical tube bundles vibration,this paper advanced an empirical correlation which predicted the critical flow velocity of fluid elastic instability,and suggested an engineering design guideline,which included the experi-mental data obtained in air crossflow by author and in water crossflow by S.S.Chen.
