摘要：
In this paper, the NACA4415 blade is used as a model. The first-order first flapping and one or two-order superimposed flapping vibration are applied to the wind turbine blades by the dynamic grid technology. The velocity distribution of the blade tip, the velocity distribution of the wake flow field, the development of wake vortex and the large eddy numerical simulation (LES) are studied. In order to study the effect of blade vibration on the aerodynamic characteristics of the wind turbine and the optimization of wind turbine arrangement in actual operation. © 2019, Science Press.
