Impulse Turbine with Self-Pitch-Controlled Guide Vanes for Wave Power Generator. Control of Guide Vanes Connected by Link Motion.

Abstract

Experimental investigations on improving the performance of the impulse turbine with self-pitch-controlled guide vanes are reported. A new type of guide vanes which are connected by link motion is presented and tested. The behavior of guide vanes in reciprocating flow is also shown relation to the axial flow velocity. The results show that a high-efficiency impulse turbine can developed by the use of guide vanes connected by link motion. Furthermore, it is found that the running and starting characteristics of this turbine in the reciprocating flow can be evaluated from the performance of the turbine with fixed nozzle and diffuser vanes in a unidirectional steady flow.
