Abstract:
A laboratory-scale study of the impact of separation distance on the performance of marine hydrokinetic turbines in a streamwise tandem arrangement is described. The study aims to give guidance concerning minimum, or optimal, turbine spacing in arrays. Testing was conducted in the hydraulic flume facility (9.8 m long, 1.2 m wide and 0.4 m deep) at Bucknell University. The devices were two-bladed model marine turbines with a rotor diameter of 0.1 m. For each separation distance, rotational speed of each device and velocity profiles of flow incident on the downstream turbine were measured. Results suggest limits for the minimum spacing between two turbines arranged in a tandem array.
