| 摘 要： | 根据200MW高温气冷堆蒸汽发生器的结构参数建立了实验研究模型,并针对相邻两层旋向相同的螺旋管管束,在横向流的冲刷下,对管子的动态响应进行了实验研究。实验结果表明,螺旋管管束的流体诱发振动响应与直管相比存在一定的差别;200MW高温气冷堆蒸汽发生器的设计避免了管束的大振幅振动。

| Abstract: | In sodium cooled reactors and high temperature gas cooled reactors (HTR), helical tube steam generator has been extensively employed because of it's advantage in tight structure, good heat transfer and small size. Based on structure parameters of 200MW HTR steam generator, the test model is established and the helical tube response in crossflow for adjacent columns in a same spin direction are investigated. The experimental results reveal the difference between helical tubes and straight tubes on flow induced vibration, and the design for 200MW HTR steam generator avoids large amplitude vibration. |
