摘要
试验时,应用相似性原理,在满足相同流动状态的前提下,采用对模型吹风的方法,建立了一套凝汽器喉部的微型模化装置。在该微型装置上,采用了不同的入口流速,对喉部出口的流场分布进行了模拟试验。首先分析了流动的稳定性,并在不同内部设备条件下,分析了喉部出口的流场分布。试验结果表明,该微型模化试验装置能够反映喉部内的流动状况,可用于其流动状态及流场分布的试验研究。
A miniature-modeling device of condenser throat is established applying the similarity principle and model blow method on the premise of same flow status. The flow distribution at throat exit is studied experimentally at different entrance velocity conditions on the device. The stability of flow is analyzed first; then the flowing distribution at throat exit is studied under different inner equipment condition. The experiment results show that the miniature-modeling device can show the flow condition inside the throat, and can be used to study the flow condition and flow field distribution of condenser throat.
