摘要 本文根据相似准则的原理建立高温气冷堆二维堆芯的球流运动试验系统,并提出了二维球流运动中界面分析的定量的实验方法,介绍了界面分析法的理论依据以及在球流内部流场研究和界面特征分析中的操作方法和过程,并且进行了不同加球比例的实验,对得到的相应的均值流线,轴向速度,径向速度,合速度,速度矢量的分布以及球流运动的特性等球流二维流动特性进行了分析,并和标志球法的结果进行了比较。 In order to study the pebble flow dynamics in the high temperature reactor core,the 2-D experiment system is set up based on the similarity criterion and the surface analysis quantitative experiment method is proposed.This paper introduces the theory basis of SAM(Surface Analysis Method) and its application in the pebble flow mechanics study.The experiment with different proportion of loading pebbles is carried out.Finally,The 2-D pebble flow characteristics including mean stream lines,velocity field distribution etc.are analyzed and compared with the results of the Marking Pebble Method.
