海上浮式垂直轴风力机的气动特性研究
Study on the aerodynamic characteristics of offshore floating vertical axis wind turbine
摘要
Abstract
The aerodynamic load of offshore vertical-axis wind turbine with floating foundation is highly complicated.Therefore,the influence of the motion of a floating foundation on the aerodynamic performance of the wind turbine should be investigated.The effects of different numbers of blades,airfoils of blade section,rotor solidity,and shapes of blade on the power coefficient of the wind turbine were discussed.The optimum structural parameters of the wind turbine were also determined.The influence of tower and the motion of a floating foundation on the aerodynamic load of the wind turbine were analyzed.A double-multiple streamtube model,which is based on blade element momentum theory,was applied to calculate the power coefficient of the wind turbine.CFD method was applied to study the aerodynamic characteristics of the wind turbine,and the results were compared with the theoretical findings.The influence of tower on power was found to be more obvious at a high tip speed ratio.The heave motion of the foundation will affect the power coefficient of the wind turbine,and the influences at different tip speed ratios vary.When the tip speed ratio increases,the difference in effects of the foundation motion of various heave cycles is gradually revealed.关键词
