【摘要】：为实现先进非能动(AP)系列安全壳的试验方案研究,根据分级双向比例分析方法(H2TS方法)开展系统级缩比分析并得出面积-体积比在缩比时的显著失真。以满足功率体积比为基本准则,运用Bottom-Up方法重点分析壳壁耦合换热现象的尺度缩比约束关系,获得表征AP系列安全壳的壳壁热量载出特性的无量纲准则群(简称П群),并以壳壁导热为例进行尺度缩比分析。对AP系列安全壳尺度缩比失真问题提出解决方案,列出尺度缩比台架需满足的基本约束关系。该尺度缩比方法可用于大尺度、大空间的模化试验分析。
[Abstract]:In order to realize the experimental scheme of the advanced non active (AP) series of containment, the system level contraction analysis is carried out according to the hierarchical bidirectional proportional analysis method (H2TS method) and the significant distortion of the area volume ratio at the contraction ratio is obtained. In order to meet the power volume ratio as the basic criterion, the Bottom-Up method is used to focus on the analysis of the scale of the coupling heat transfer phenomenon of the shell wall. The dimensionless criterion group that characterizing the heat load characteristic of the shell wall of the AP series containment is obtained, and the scale contraction analysis is carried out with the shell wall heat conduction as an example. The solution of the scale contraction distortion problem of the AP series containment scale is put forward, and the basic constraint relation of the scale contraction platform is listed. The scale shrinkage method is listed. It can be used for the model test analysis of large scale and large space.
