Recent innovations in the off-shore wind industry have lead to bigger wind turbines and taller support structures. These towers can suffer from vortex-induced vibrations (VIV). The present work couples the open-source CFD solver OpenFOAM with a structural solver to investigate these fluid-structure interactions (FSI) effects in more detail. 2D...

Flow induced vibrations (FIV) is a known problem in nuclear reactors. The interaction between the turbulent flow of the coolants and the fuel rod bundles generates vibrations which are undesirable. These vibrations can be a major cause of fatigue failures, stress corrosion cracking and fretting wear of materials, which lead to stand-still costs....

The ERCOFTAC test case for flow past a square-prism at a Reynolds number of 21,400 was studied numerically using the flow solver ReFRESCO. The main objectives were to evaluate the performance of a Reynolds Averaged Navier-Stokes (RANS) based turbulence models in Unsteady RANS (URANS) simulations, identify sensitivities to numerical parameters...

Moonpools are vertical wells used on most offshore vessels at Huisman Equipment. The oscillations in the moonpool lead to a significant increase in resistance for vessels in transit conditions. In the concept design phase it has proven difficult to predict the moonpool behaviour, as well as the effect of implementing appendages within a long...

In order to ramp up the conversion ratios and burn-up of nuclear reactors, it is inevitable to go to tightly packed fuel rods in the reactor. These nuclear reactors with tightly packed rod-bundles are characterized by interesting flow patterns, different from the ones encountered in regular channel and pipe flows. The correct prediction and...
