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。 Spiral tube steam generator because of its structure, heat transfer performance and other advantages in the fast reactor and high temperature gas-cooled reactor is widely used. Based on the experimental study on the induced vibration of the spiral tube bundle, the experimental data of the spiral tube bundle scouring in the transverse airflow and the experimental data of the American Argonne Laboratory S were obtained. S. Chen Under the scouring of lateral flow, experimental data of semi-empirical fluid elastic instability of spiral tube bundle and design criteria for practical application are established.
