Impulse Turbine With Self-Pitch-Controlled Guide Vanes For Wave Power Conversion: Performance Of Mono- Vane Type

TLDR: In this paper, an impulse turbine with self-pitch-controlled guide vanes was investigated experimentally by the use of turbine test equipment in which the sinusoidally reciprocating flow conditions are simulated.

Abstract: An impulse turbine with self-pitch-controlled guide vanes was proposed by the authors in a previous paper. The unsteady characteristics of this turbine have been investigated experimentally by the use of turbine test equipment in which the sinusoidally reciprocating flow conditions are simulated. The results have been compared with those of a Wells turbine. Furthermore, in order to clarify the usefulness of quasi-steady analysis of this turbine, they have been also compared with the analytical results calculated on the basis of the experimental data obtained by the model testing of a turbine rotor with fixed guide vanes under steady unidirectional flow conditions. As a result, it has been clarified that the impulse turbine presented here is superior to the Wells turbine in overall characteristics, and the quasi-steady analysis is available for this turbine.
