Abstract

Abstract

The governing equations for the natural circulation processes in the secondary passive residual heat removal system（PRHR） were derived in this paper.With proper reference parameters,the equations were nondimensionalized and the similarity groups for the system were achieved.The specialty of the study is the treating of the two coupled natural circulation processes.The choosing and nondimensionalization of the en-ergy equation has also some advantages over the existing researches.
