Abstract

Abstract

In this paper, the flow characteristics throughout a PWR 3x3 rod bundles was investigated, and four turbulence models including SST,SSG-RSM,BSL-RSM and ω-RSM were used to simulate in steady state and then evaluated with the laser Doppler measurement data of the flow. The comparisons demonstrate that BSL-RSM and SSG perform better relatively though still having some errors in predicting the turbulent fluctuation.
