Biplane axial turbine for wave power generator. (Aerodynamic characteristics of noncambered blades).

Abstract

Experimental investigations directed towards improving the overall characteristics of the turbines for wave power generators are reported. Biplane axial turbines with variable setting angles have been manufactured and tested to investigate the effects of the blade setting angle, gap to chord ratio, solidity and arrangement of biplane rotor on the turbine performance. The results have been compared with those of the air turbine with self-pitch-controlled blades and biplane Wells turbine. A suitable choice of the design factors has been suggested.
