Abstract

Abstract

Many challenges exist in the CFD simulation for the whole pressurized water reactor（PWR）. For instance, the simulation distortion will occur without the fine mesh scheme, but it is time consuming to design and select the fine meshes for various complicated structure zones in the core. CFD simulation of the whole PWR core requires more than 60 billion meshes, which costs massive computing resources and time. To reduce the burden, two schemes were developed. One is the multiple RANS scheme. The other one is based on the structure simplification and simulation modification. Both schemes can give the accurate results and reduce a lot computing burden.
