Abstract

Various global studies have shown that marine currents have large potential as a predictable sustainable resource for commercial scale generation of electrical power. For successful exploitation of this resource, an understanding of the hydrodynamics of the marine current turbine is of primary importance. Although a lot can be learned from the technology transfer from wind turbines and ship propellers, there has been limited hydrodynamics research for this particular application. A methodology is presented for the hydrodynamic design of horizontal axis marine current turbines. Recent research has investigated the performance of suitable 2D section shapes both experimentally in a cavitation tunnel and with numerical simulations. A numerical model of a typical 3D rotor is used to demonstrate parametric variations of the design parameters and the use of alternative blade sections.
