| 中文摘要 | 以清华大学研发的多用途小型堆NHR为基础,建立全尺寸、全参数1∶1自然循环试验回路研究零功率摇摆条件下自然循环的流动规律。通过分析几组不同摇摆运动下的实验结果,探讨了单自由度摇摆运动摆角幅值ψm和摇摆周期T对自然循环速度的影响,并给出自然循环流速波幅Vo和摇摆运动参数ψm与T之间的线性关系。研究结果表明:ψm对加热段两侧流速影响最为显著,Vo随ψm的变大而增大且两侧流速波动相位相差90°;Vo随T的增大而减小,流速波动相位差与T无关;在零功率摇摆条件下,流速波幅的平方V2o与ψm、频率平方w2d及当量摇摆半径Req的乘积呈线性关系。; Based on a multi-purpose small nuclear reactor(NHR)developed at Tsinghua University,a natural circulation experimental loop to study the characteristics of natural circulation under rolling condition with zero power was built.The effect of rolling angleψmand rolling cycle T of single-freedom rolling motion on natural circulation was explored through the analysis of several groups of experimental results,and the linear relationships between flow amplitude Voand rolling motion parametresψm and T were given.The results indicate that the obvious influence of rolling angleψmon flow velocity of two-side channels of heating section is observed,and flow velocity wave amplitude Vo increases withψm.Vo decreases with the increase of T,and the wave phase of flow velocity fluctuation is unrelated with T.In rolling condition with zero power,a linearrelationship between the V2 oand the product ofψm,the square of frequency w2 dand the equivalent rolling radius Reqis proved. |
