This paper presents results from numerical simulations of a 3-bladed horizontal axis tidal
stream turbine. Initially, Reynolds Averaged Navier Stokes (RANS) k–ω Shear Stress …

This Thesis presents simulation of flow past laboratory-scale and full-scale tidal stream
turbines (TST) using EDF's open-source CFD solver Code_Saturne. The work shows that …

The unsteady hydrodynamics of tidal stream turbines have been investigated using
numerical methods and experiments. Dynamic inflow, which represents the change in …

This thesis considers the effect of disruptive waves and turbulence on a horizontal axis tidal
stream turbine (TST), in terms of performance and survivability. The TST reaction to transient …

Predictions of expected unsteady loads on tidal turbines are vital for ensuring longevity of
installed devices. In addition, the acoustic signature of turbines has become a design …

Darrieus rotor is a promising technology for hydrokinetic and wind energy harvesting
applications. However, the Darrieus rotor suffers from the problem of poor starting …

Horizontal axis tidal turbines (HATTs) must provide reliable electrical energy production in a
subsea environment with minimal maintenance. Failures related to turbine blades will have …

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 …

In order for the tidal stream energy sector to achieve commercial maturity, procedural
improvements must be made in order to increase economic viability. This thesis targets the …

The idea of extracting useful, utility scale, energy from tidal currents has been the focus of
much research and development over the past couple of decades. From the 1990s desk …
