Ezperimental Study on a Direct Drive Turbine for Wave Power Converter System

摘要：

Performance and internal flow of a direct drive turbine (DDT) model for wave power converter systeM is investigated experimentally. Three kinds of test turbine model are adopted for the examination. Test results show that rotational speed of test runner, differential pressure between front and rear nozzle passages and passage flow rate increase by the increase of wave height and wave period. MaximuM output power and best efficiency of the test turbine model locate at the different rotational speed by wave height. Installation of front guide wall and rear water reservoir of the test turbine improves the turbine performance. Large passage vortex occurs both at the front and rear nozzle passages in turn by reciprocating flow in the internal flow passage of the turbine model.
