摘要 以超临界水堆传热关系式为基础,利用模糊数学中贴近度的概念,设计了贴近度计算模型。应用该模型,比较了临界水堆实际工况与各经验公式适用范围的贴近程度,获得了实际工况下最为适用的经验关联式以及与实际最相符的结果。由此表明,模糊数学中贴近度的应用,为超临界水堆的流动传热问题提供了一种可以在已知关联式的基础上做出针对实际工况的最优关联式选择方法,使计算结果更为精确。 Base on the correlations of supercritical water reactor, using the degree of similarity, which is included in Fuzzy Mathematics, a new calculation model for calculating the degree of similarity between. actual status and the empirical correlations is designed. By this model, the actual status is compared with the empirical correlations, and the best correlation for actual status is obtained. It is indicated that the degree of similarity can be used in the choosing of the best correlations for the problem about heat transfer of supercritical water-cooled reactor, based on the known correlations, resulting in the results with higher accuracy.
