摘要
研究了闭式自然循环实验回路单相流动阻力的系统特性。结果表明：在本文的实验参数范围内，以一维充分发展强迫流动关系式为基础的计算结果与实验结果相比有一定的偏离，这与ＲＦＬＡＰ５／ＭＯＤ２程序对ＬＳＴＦ等装置及ＤｏｅｌＰｌａｎｔ的分析结果基本一致。建立了自然循环流动阻力系统特性的归一化分析数学模型对实验数据进行归一化分析，得到了一组新的自然循环系统等效摩擦阻力系数的经验关系式。本文较大地拓宽了该基础研究领域的实验数据范围，从系统的角度确证了自然循环与强制流动存在的差别并分析其机理成因，结论可供先进反应堆的研究和设计参考。
The system performance of single-phase flow resistance in a natural circulation experimentalloop is investigated. It is shown that the results calculated by the correlations of one-dimensionalfully developed forced flow differ from this experimental data within the range of experimentalparameters, basically in agreement with the results of using PELAP5/MOD2 to analyse LSTFand Doel Plant. A normalized analysis model of system performance of flow resistance in naturalcirculation is developed. The experimental data are analysed by this model and a new experimentalcorrelation of equivalant frictional coefficient in natural circulation loop is developed. The range ofexperimental data of this foundational resesarch is extended in this paper, The difference of systemperformance of flow resistance between natural circulation and forced circulation is confirmed andits mechanism is analysed. The results of this paper may be helpful for the research and design ofadvanced reactor.
