A radical flow self rectifying air turbine

A novel type of self rectifying air turbine incorporating aerofoil blades has been developed. This turbine offers the possibility for varying the flow duct area to maintain the air velocities as the wave driven flow rate changes. This is particularly suitable for wave energy conversion as wave power levels vary considerably from day to day. A small model of this turbine has been constructed and initial testing has been carried out in unidirectional flow.
Further testing of the concept is required to prove the viability and determine actual efficiencies for the machine. The present model could be tested in a facility with air blower capability larger than is available in Cork.
