Abstract
Wells turbine is an axial flow bi-directional turbine used for wave energy conversion by Oscillating Water Column (OWC) system. Different variations of Wells turbine have been studied and tested to find out the best rotor geometry. A comprehensive review of Wells turbine is presented here to familiarize the reader with the state of the art of Wells turbine. Turbines are broadly classified into two types: monoplane and biplane, with further classifications including attachment of guide vanes and variation of blade pitch angles. Numerical optimization works carried out on air turbines for wave energy system are also presented in this chapter. Turbines with optimized geometry give a better performance compared to standard turbines in terms of overall system performance, efficiency, and energy absorption.
