System design and optimization study of axial flow turbine applied in an overtopping wave energy convertor. (English) Zbl 1339.94016
Summary: The axial flow turbine applied in an overtopping wave energy convertor can continuously provide power with high efficiency and reliably. To study the rules between parameters of the turbine and flows, three different types of turbines with complete 3D flow-channel models were designed and optimized. It appears that diameter of the runner, flow rates, number of guide vanes and shape of outflow passage have a considerable impact on the performance of the whole convertor. The turbine with a diameter of 0.8 m, flow rate of 0.5 m\(^{3}\)/s, double guide vanes and bent section in outflow passage shows the best comprehensive performance. Moreover, the results of the experiments indicate that the output power can be enhanced by increasing the wave overtopping rate.
