GTRF Calculations Using HydraTH (THM.CFD.P5.05)
Abstract
This report describes the work carried out for completion of the Thermal Hydraulics Methods (THM) Level 3 Milestone THM.CFD.P5.05 for the Consortium for Advanced Simulation of Light Water Reactors (CASL). A series bodyfitted computational meshes have been generated by Numeca's Hexpress/Hybrid, a.k.a. 'Spider', meshing technology for the V5H 3x3 and 5x5 rod bundle geometry used to compute the fluid dynamics of gridtorod fretting (GTRF). Spider is easy to use, fast, and automatically generates highquality meshes for extremely complex geometries, required for the GTRF problem. HydraTH has been used to carry out largeeddy simulations on both 3x3 and 5x5 geometries, using different mesh resolutions. The results analyzed show good agreement with StarCCM+ simulations and experimental data.
