Simulation Analysis of Flow Field and Aerodynamic Characteristics of Large Wind Turbine
摘要
Abstract
The aerodynamic load on the wind turbine is related to the flow field around the wind turbine.The alternating loads such as aerodynamic load and elastic force of the wind turbine cause the vibration deformation of flexible wind wheel,tower and other components.The vibration deformation of wind turbine components affects the flow field around the wind turbine,which puts forward higher requirements for wind measurement technology of wind turbine,and high-resolution wind speed prediction is of great significance to the control and load calculation of wind turbine.In this paper,Computational Fluid Dynamics simulation(CFD)based on sliding mesh and Fluid Structure Interaction simulation(FSI)based on dynamic mesh are used to study large-scale wind turbine,and explore the relationship between the deformation behavior of flexible blades and the evolution of flow field,which can reduce the cost of field test and wind tunnel test and provide verification data for wind speed prediction model.The simulation results show that the inflow effect and wake effect of wind turbine simulated by CFD and FSI are close to the theoretical value.FSI simulation can simulate the amplitude and position of the maximum stress and maximum strain of the wind turbine.关键词
