Numerical Simulation And Experimental Study Of Hydrodynamic Characteristics In Marine Current Energy Converters

Ocean energy is a kind of renewable energy which is contained inocean, with many advantages, such as rich reserves, wide distribution,clean, no pollution and so on. Marine current energy is a clean andrenewable energy, which is one of the most exploitable and flexible oceanenergy. Exploiting the technology of Marine current energy to generateelectricity is helpful for improving the energy structure and reducing thepollution and climate change which is brought by fossil energyconsumption. Hydrodynamic characteristic of marine current energyconverters’ wing section of one-way blade is the key factor to developand utilize of marine current energy.At present, the domestic and foreign research on the marine currentturbines mainly focuses on the relation between turbine blade airfoilgeometric parameters and rotational speed, but research on hydrodynamiccharacteristic of converter is rare. This paper based on the one-way blades of marine current energy converters which designed byhydraulics laboratory in Zhejiang University of Technology, applyingcommercial CFD software FLOW-3D to simulate the hydrodynamiccharacteristic of marine current energy converters. The numericalsimulation of the hydrodynamic characteristic of One-way blade underslow flow speed is done, and get the velocity distribution， pressuredistribution, turbulent energy in airfoil internal flow field. Meanwhile,at the multi-function toughened glass sink, applying advancedexperimental instrument to measure and analyse the inner flow field ofone-way blade, such as DANTEC-PIV、PHOTRON APX-RS、SONTEKADV and so on. Then, compared and analyzed two kinds of results.
