CFD Analysis for the PWR Rod Bundle with Split-Type Mixing Vanes

摘要

The EPRI-led CFD round robin benchmark exercise against the NESTOR experiment for a PWR rod bundle has been recently completed. This project has great advantages in that (ⅰ) the round-robin type validation enables us to test and compare various CFD methodological factors and thus to obtain overall insights into CFD capabilities and limitations; and (ⅱ) the NESTOR experiment has broad-range, accurate measurements of rod inner-surface temperatures as well as flow field under the thermal hydraulic conditions comparable to typical PWR ones.
