As a continuation of the first set of tests to provide further detailed design information and validation date for numerical models a new experimental test rig was developed. This test rig has been designed, built and successfully used to measure power and thrust on model tidal turbines under various configurations and flow conditions. The setup […]
A scale model a horizontal axis marine current turbine was tested at the circulating water channel facility at QinetiQ in Hampshire. The model was scaled such that the ratios of the rotor diameter/water depth and the blade tip speed/inflow speed were equal to that of a full scale device. The three bladed rotor depicted was […]
Portland Bill on the South coast of the UK (view in maps.live.com) is a promising site for tidal stream energy, with high tidal stream velocities of up to seven knots (3.6 m/s) around the headland. Although the area with high tidal streams is smaller than other proposed sites in Scotland or the Channel Islands, the […]
Section performance data, which also include cavitation characteristics, are required for the detailed design of the turbine blades. It is found that suitable published data, with cavitation characteristics, are very limited and that there is a need to establish a better understanding of the cavitation performance of 2-D sections suitable for marine turbines. It is […]
