Large Eddy Simulation Of Tidal Turbines

, 2017
Understanding of hydrodynamics involved in the ow around tidal turbines is essential to enhance their performance and resilience, as they are designed to operate in harsh marine environments. During their lifespan, they are subjected to high velocities with large levels of turbulence that demand their design to be greatly optimised.

Optimal design of a tidal turbine

IOP Conference Series: Earth and Environmental Science, 2012
An optimal design procedure has been applied to improve the design of an open-center tidal turbine. A specific software developed in C++ enables to generate the geometry adapted to the specific constraints imposed to this machine. Automatic scripts based on the AUTOGRID, IGG, FINE/TURBO and CFView software of the NUMECA CFD suite are used to evaluate ...

Tidal turbine array modelling

, 2014
Computational fluid dynamics (CFD) is used in this thesis to model wind and tidal stream turbines and to investigate tidal turbine fence performance. There are two primary objectives of this work. The first is to develop and validate an actuator line method for the simulation of wind and tidal turbines which applies the blade forces to the flow field ...
