Hydraulic structures can be a promising place for tidal energy extraction due to the high flow velocities, easy
access to the power grid and easy access for maintenance. However, quantification of the impacts of a tidal power
plant in a hydraulic structure is not straight forward. In 2015 a pilot plant consisting of an array of five Tocardo
tidal t...
Salt water intrusion through the New Sea Lock of IJmuiden, Netherlands requires mitigation to ensure availability of enough fresh water further inland. For this purpose, a salt screen has been proposed for selective withdrawal of salt water from the
Noordzeekanaal in the vicinity of the lock complex. Formulas to assess the withdrawal rate of selec...
To estimate the impact on energy production and environment of tidal turbines placed in the Eastern Scheldt Storm Surge Barrier a Computational Fluid Dynamics (CFD) study has been carried out on the additional head differences induced by the turbines. The CFD model focusses on a single gate opening of the Storm Surge Barrier and includes half of th...

In the presentation we discuss how flow separation downstream of irregular bathymetric features affects the theoretical power that can be extracted from a barrier, using results from a Computational Fluid Dynamics (CFD) model of the full scale tidal turbines which are installed in a Dutch storm surge barrier. Possibly, more power can be extracted f...
The discharge coefficient is a determinative parameter in the prediction of forces on ships in a lock chamber during levelling. In this paper, the application of CFD to establish the discharge coefficient a priori has been validated. To this end, a comparison has been made to measurement of a scale model of a lock gate with gate openings. Various t...
This paper reports results from the application of Computational Fluid Dynamic (CFD) simulations of a leveling process in a sea lock using a fully 3D finite volume code (Star-CCM+). The model incorporates a free surface in the lock, saltwater density effects by means of a transport equation for salt, a turbulence model validated for negatively buoy...
Large-Eddy Simulations (LES) were carried out for a turbine rim seal and
the sensitivity of the results to changes in grid resolution and the
size of the computational domain are investigated. Ingestion of hot
annulus gas into the rotor-stator cavity is compared between LES results
and against experiments and Unsteady Reynolds-Averaged
Navier-Stoke...
Unsteady flow dynamics in turbine rim seals are known to be complex and attempts accurately to predict the interaction of the mainstream flow with the secondary air system cooling flows using computational fluid dynamics (CFD) with Reynolds-averaged Navier–Stokes (RANS) turbulence models have proved difficult. In particular, published results from...
