Impulse Turbine with Air Flow Rectification System for Wave Power Conversion

Abstract

In order to develop a high performance impulse turbine with air flow rectification system for wave power conversion, the impulse turbine has been designed and investigated experimentally by model testing. Then' the running and starting characteristics in irregular ocean waves have been evaluated by a computer simulation, taking account of energy conversion efficiency of oscillating water column. As a result, a suitable choice of design factors has been suggested for the setting angle of guide vane and rotor profile.
