升力型垂直轴风力机相互作用研究
Investigation of Interaction between Lift-type VAWTs
摘要
Abstract
The transient computational fluid dynamics (CFD) was carried out to study the interactions between two vertical axis wind turbines(VAWTs) at different distances.The pressure fields and the vorticity fields of the two wind turbines in one-third rotation period were also analyzed.The results indicate that the unsteady wake flows of the rotor No.1 will affect the pressure fields and vorticity fields of the rotor No.2 significantly.This wake flow effects on the rotor No.2 are weakened with the increasing of the distances.That is the reason why the power coefficient of the rotor No.2 is increased with the distance increasing.When the distance is equal to 6D (D is the diameter of the rotor),the maximum power coefficient of the rotor No.2 is approximately equal to that of the rotor NO.1.关键词
