摘要
不考虑连杆和转轴以及叶尖损失的影响,采用雷诺平均Navier-Stokes方程和k-ωSST湍流模型对直叶片垂直轴风力发电机风轮进行二维数值模拟,考虑风轮处于不同来流风速时,三叶片与五叶片风轮流场分布及压力场分布的异同。为后续研究提供良好的指导方向。
Without regard to loss of rod and shaft, as well as the impact of tip, using Reynolds-averaged Navier-Stokes equations and k-ω SST turbulence model , straight blade vertical axis wind turbine for two-dimensional is simulated. Considering the wind wheel to flow at different wind speed, the three-blade and five-blade wind turns the field distribution and pressure field distribution of the similarities and differences. The aim is to provide a good orientation for the follow-up study.
