Aerodynamic Performance of Contra-Rotating Wells Turbine for Wave Energy Conversion

A contra-rotating Wells turbine as an alternative to a biplane Wells turbine for wave energy conversion is investigated. The aerodynamic analysis and control of such a turbine are presented. It is shown that for a given pressure amplitude a contra-rotating Wells turbine is aerodynamically more efficient and can operate over a wider range of flowrates when compared to a biplane Wells turbine.
