Nek5000 Large-Eddy Simulations for Thermal-Hydraulics of Deformed Wire-Wrap Fuel Assemblies

摘要

As a part of a larger collaborative validation project with TerraPower, Texas A&M University, and AREVA, we have presented LES results for undeformed single wire-wrap 61-pin geometry. Pre-test Nek5000 isothermal simulations are carried away in the range of Reynolds numbers from Re = 3,000 to 15,000 and will be soon compared to the con-current experiment data. The undeformed conjugate-heat-transfer and deformed simulations are under way.
