摘要

本文利用ANSYS Fluent 6.3.26软件对aH-Darrieus型三直叶垂直轴风力机进行了计算研究。为了确定固体度对风力机气动性能(静扭矩系数和静压)的影响，进行了二维CFD仿真。给出了Realizable k-ε湍流模型对0.47 m、0.53 m和0.6 m三种桨叶弦长构型的仿真结果。结果表明:叶片弦长越小，静扭矩系数越小，静扭矩系数随弦长增大而增大

Numerical Study of the Aerodynamic Performance of a Stationary H-Darrieus-Type Vertical-Axis Wind Turbine

This paper presents a computational study of aH-Darrieus vertical axis wind turbine with three straight blades by using ANSYS Fluent 6.3.26 software. Two dimensional (2D) CFD simulations were carried out in order to determine the effect of solidity on the aerodynamic performance (statictorque coefficientand static pressure) for wind turbine. The simulation results with the Realizable k-ε turbulence model are presented for three configurations of the blade chord length with 0.47 m, 0.53 m and 0.6 m. The results show that thesmall blade chord length presents a lower static torque coefficient, which increases with the increasing of the blade chord length.1
