Numerical simulations of vortex-induced vibrations in a 7-rod bundle compared to experimental data Universiteit Gent
Being able to quantify mechanical vibrations is of key importance for the safety of nuclear power plants, as they are able to induce damage. In this work, numerical simulations are used to simulate water flow through a densely packed bundle of 7 rods, mimicking an experimental setup used at Delft University of Technology. This flow configuration is chosen to resemble the coolant flow through a nuclear reactor core. Because of the wall proximity, ...
