Canadian Participation in OECD/NEA-KAERI Rod Bundle Benchmark for CFD Codes

Abstract

Three submissions to the latest international benchmark exercise for computational fluid dynamics (CFD) codes used in nuclear safety applications were produced in Canada by three independently working research teams. The teams used different commercial CFD codes or code versions, different meshing tools and techniques, different turbulence modeling options and different computer resources. The paper describes the three modeling strategies and presents sample comparisons between the three solutions submitted to the blind benchmark.
