摘要:
 建立了五叶片垂直风力机三维模型，采用滑移网格技术对五叶片垂直风力机的气动性能进行分析。研究结果表明，叶片的半径和高度会对风力机外围的速度场及湍动能分布产生明显影响，进而影响风力机的风能利用率。不同转速的风力机随着叶片宽度的增加其风能利用率呈现先增加后减小的趋势，同时在风力机转速一定情况下，风力机的风能利用系数随着叶片高度的增加也呈现明显的先增加后减少趋势。
Abstract:
The three-dimensional model of five-blade vertical wind turbine was established, and the aerodynamic performance of five-blade vertical wind turbine was analyzed by sliding mesh technique. The results show that the radius and height of the blade will greatly influence the velocity field and the turbulent kinetic energy distribution in the periphery of the wind turbine, and then influence the wind energy utilization rate of the wind turbine. With the increase of blade width, wind energy utilization of wind turbines at different rotational speeds increases first and then decreases. At the same time, the wind energy utilization coefficient of wind turbines increases with the increase of blade height and then decreases.
