Abstract

OutFlow Radial (OFR) Turbines have been recently proposed for Oscillating Water Column (OWC) devices based on a Twin Turbine Configuration (TTC). Previous experimental studies showed that these turbines are a feasible alternative to axial unidirectional turbines without rectifying systems.
