Abstract
The paper outlines the development and testing of a 0.9 m diameter lab-scale Horizontal Axis Tidal Turbine. The turbine was developed based on design experience acquired at Cardiff University during the development and testing of a number of legacy lab-scale Horizontal Axis Tidal Turbines. The development process was also considerate of design activities undertaken elsewhere within research. The development of the aforementioned Horizontal Axis Tidal Turbines was undertaken specifically to test under dynamic lab-scale conditions including both wave, turbulence and, ultimately, dynamic loadings caused by array interaction effects.
