The wave energy devices currently being built in United Kingdom and elsewhere have adopted the Wells air turbine for converting pneumatic energy in the device to mechanical energy of rotation. A monoplane (single plane) Wells turbine can absorb only a certain maximum pneumatic pressure amplitude due to tip speed limitations. For wave energy devices which produce large pneumatic pressure amplitudes a biplane Wells turbine with or without guide vanes can be used. An alternative to a biplane is a contra-rotating rotor. The aerodynamic performance and control of such a rotor are discussed.
