中文摘要: 选用NREL 5 MW风力机,采用FLUENT软件对塔筒式和桁架式两种塔架的风力机整机进行了非定常数值模拟。结果表明:桁架受到的升力和阻力都远小于塔筒,桁架式的结构更有利于自身安全;气流在通过桁架后的速度梯度和湍流强度都大于塔筒式风力机,而不同截面的速度都略小于塔筒式风力机。因此,桁架式风力机的布置间距要考虑略大于塔筒式风力机的布置间距。

Abstract:The NREL 5 MW wind turbine is chosen and unsteady numerical simulation of tower shadow effect of monopile and truss type tower wind turbine are carried out by using FLUENT software.The results show that the lift and drag of the truss type tower are far less than the monopile type tower,so truss structure is more conducive to their own safety.The velocity gradient and the turbulence intensity of airflow is greater than the monopile type tower wind turbine when it passes truss type tower wind turbine,but the velocity of different sections is slightly smaller than the tower type wind turbine.So the layout spacing of the truss type tower wind turbine should be slightly larger than the monopile type tower wind turbine layout spacing.
