Abstract
Experimental investigations directed towards improving the performance of a biplane Wells turbine for a wave power generator are reported. Three turbine configurations consisting of (a) a biplane rotor with outer guide vanes, (b) a biplane rotor with inner guide vanes, and (c) a triplane rotor were tested. The results have been discussed from the viewpoints of starting characteristics, running characteristics and stall margin. Most of the configurations tested have shown improvements in the operation range due mainly to postponement of stall. The most preferable configuration is the biplane rotor with outer guide vanes, for which a suitable choice of design factors has been suggested.
