Analysis of aerodynamic and power characteristics of a dual-rotor wind turbine
摘要
Abstract
In order to study the aerodynamic characteristics of a dual-rotor wind turbine,this paper first built a dual-rotor wind turbine model based on the NREL 5 MW and WindPACT 1.5 MW wind turbine rotors using Solidworks,and used Fluent to simulate the flow field characteristics of the dual-rotor wind turbine;then,the flow field characteristics of the dual-rotor wind turbine and the NREL 5 MW single-rotor wind turbine were compared and analyzed;further,the flow field characteristics of two dual-rotor wind turbines and two single-rotor wind turbines with the same tandem layout were compared and analyzed.The results show that the dual-rotor wind turbine has a higher wind energy utilization rate,a faster wake recovery speed,and a small turbulence intensity at the center of the rotor;for the two dual-rotor wind turbines with a tandem layout,the total power of the two dual-rotor wind turbines is greater than that of the two sin-gle-rotor wind turbines with the same layout at three wind speeds.关键词
