蒸汽发生器实验回路倒流特性仿真分析
Numerical Simulation and Analysis of Reverse Flow in Steam Generator Experiment Loop
摘要
Abstract
For the reverse flow phenomenon in the vertically inverted U‐tube steam gen‐erators ,a new node partition scheme was used to model the steam generator test section based on the system analysis code RELAP5/MOD3.3 .The reverse flow phenomenon in the process of experiment was simulated in this paper .Compared with the experimental data ,the correctness of the new scheme developed in this paper was verified . The results show that the reverse flow phenomenon occurs in the shorter U‐tubes . For single U‐tube ,the mass flow rate of reverse flow is generally greater than that of nor‐mal flow U‐tube .When the reverse flow occurs ,the system will get into a relatively stable state .However ,the negative pressure drop between the inlet and outlet plenums and the heat exchange of test section reduce significantly .关键词
