Open AccessThe objective of the present investigation is the numerical prediction of the potential of a flow to inflict surface damage by cavitation. For this purpose, physical criteria are derived that detect and quantify relevant ... -
Exploratory RANS simulations of partial cavitation and its dynamics
(2011)
Conference report
Open AccessPartial cavitation on a 2D foil at given incidence goes through various stages when the cavitation number is lowered. This paper explores by numerical simulation the transition from more or less steady to dynamic behaviour, ... -
Numerical and experimental investigation into propulsion and cavitation performance of marine propeller
(2011)
Conference report
Open AccessThis paper discusses the application of the CFD to transitional and cavitating flow around marine propellers. Especially the emphasis is put on the adaption of the 3 equations turbulence model for the non-cavitating flow ... -
A mesh adaptive compressible euler model for the simulation of cavitating flow
(2011)
Conference report
Open AccessWe present computations of cavitating flow over a NACA0015 hydrofoil. The simulations are performed by a finite volume compressible Euler model with dynamic mesh adaptation. The adaptive mesh refinement (AMR) is driven ... -
Advances in the development of a time-domain uns ructured finite element method for the analysis of waves and floating structures interaction
(2011)
Conference report
Open AccessBeing capable of predicting wave-structure interaction in the time domain is of great interest for the offshore industry. However most computer programs used in the industry work in the frequency domain. Therefore, the ... -
Efficient numerical simulation of offshore structures and wind turbines on general purpose graphics processing units
(2011)
Conference report
Open AccessOffshore wind turbines are complex systems that are usually simulated in the time-domain to take account of non-linear effects. The response of the structure is calculated by the finite-element method, or with the more ... -
The variation in wake structure of a tidal stream turbine with flow velocity
(2011)
Conference report
Open AccessA combined Blade Element Momentum - Computational Fluid Dynamics (BEM-CFD) model is applied to a 10 m diameter tidal stream turbine blade and the supporting nacelle and tower structure in a 700 m long rectangular channel. ... -
Analytical and computational approach for studying the interaction between waves and cylindrical wave energy converters oscillating in two modes
(2011)
Conference report
Open AccessOcean wave energy may be recovered by oscillating wave energy converters. The energy converter studied in this work is a horizontally orientated cylinder which may be placed at different depths in the sea. The cylinder ...
