Study and experiment of wave-flow integrated power-generation unit
摘要
Abstract
In order to enhance the efficiencies of both energy capture and energy conversion for improving the influence from the hydro-turbine blade on the flow-field performance,a bidirectional wave-flow integrated power-generation unit is proposed herein with the methods of ANAYS simulation in fluid dynamics and experimental comparison by taking developing the power-generation equipment technology for ocean renewable energy as the target.Without the intermediate accelerating mechanism,a flexible direct-drive permanent magnet generator is applied to the device,and then the small modular power supply is realized,which enhances the energy conversion efficiency of the hydro-turbine.For enhancing the energy coefficient of the hydro-turbine and optimizing the flow-field performance,a bidirectional flow-deflector is designed,for which the influences of various spread-angles of the flow-deflector on the flow field are studied with the relevant simulative analysis,furthermore,the simulations are made for the flow-deflectors with various spread-angles,thus the optimal spread-angle for the flow-deflector is obtained.The result from the relevant flume experiment shows that the value of the maximum power point depends on the structural parameters of the impeller blade,the size of the flow-deflector and the efficiency of the electromotor.Adding flow-deflector can lower the interference from fluid turbulence and improve the operation effect of the impeller under the environment of flow field.The optimal angle of the flared hood for the flow-deflector is near 25°.The device has the characteristics of better low-speed starting performance,non-commutation,high efficiency,etc.,and it can be used under the conditions of lower flow rate and bidirectional inflow.关键词
