Studies on Wells Turbine for Wave Power Generator : Part 3; Effect of Guide Vanes

Abstract

In order to improve the performance of a Wells turbine the effects of guide vanes with circular-arc profile have been investigated experimentally by model testing under steady operating condition. The experimental results have been compared with those of the case without guide vanes. It is found that the running characteristics as well as the starting characteristics are considerably improved by the guide vanes. The improvement is mainly due to diffuser effect of the outlet guide vanes.
