원자로 외벽냉각시 원자로공동에서의 자연순환 이상유동에 대한 수치적 연구

다국어 초록 (Multilingual Abstract)

This work presents a numerical analysis of two-phase natural circulation flow in reactor cavity under<br/>
external vessel cooling. Steady, incompressible, three-dimensional Reynolds-averaged Navier-Stokes<br/>
equations for multiphase flows with zero equation turbulence model are solved to predict the shear key effect<br/>
on the circulation rate of cooling water and the distribution of void fraction according to the different mass<br/>
flow of inlet air. Results show that shear key has a positive effect on the circulation rate of cooling water and<br/>
induce a local increase of void fraction below the shear key, but not remarkably.
