The development of a blade element momentum (BEM) model for the hydrodynamic design of marine current turbines is presented. The model includes routines for interpolation of 2D section data and extrapolation for stall delay. The numerical model is compared with experimental data obtained from...

The conversion of the kinetic energy presented by ocean or marine currents offers an exciting proposition as it can provide regular and predictable energy resource. The majority of the proposed designs for converting this type of kinetic energy are based on the concept of the horizontal axis...

The results of cavitation tunnel and tank tests on an 800mm diameter model of a marine current turbine (MCT) are presented. The tests were carried out in a 2.4m×1.2m cavitation tunnel and the 60m towing tank. Results for power and thrust coefficients are presented for a range of tip speed ratio...

Portland Bill (Dorset, UK) is a promising site for tidal stream energy exploitation; it combines high tidal stream velocities around the headland with a location closer to population centres than other proposed sites. To better estimate available energy resources at the site, a two-dimensional...
