【摘要】 开展了模拟准则的研究,基于双向多级模化(H2TS)模化研究方法,对蒸汽发生器(SG)自然循环相似准则进行深入研究。根据实验目标所关注的物理过程,建立了物理现象识别和分级表(PIRT),推导了SG自然循环遵守的守恒方程,通过无量纲化得到了相似准则数并结合实验对其进行了分析和简化。更多还原

【Abstract】 The research of the simulation criterion about natural circulation was introduced based on the hierarchical two-tired scaling(H2 TS) methodology.According the physical process of experiment target,the phenomena identification and ranking tables(PIRT) was established.Steam generator(SG) natural circulation equation was deduced,dimensionless similarity critera was obtained.The similarity criteria was analyzed and simplified based on experiment test.更多还原
