| 内容記述 | The traditional method of flutter analysis of wind turbine blades employs a mixed-domain (frequency- and time- domain) formulation for self-excited aerodynamic loads, because flutter derivatives are functions of reduced frequencies. However, a time domain formulation for self-excited and buffeting loads allows the equations of motion to be continuously solved for response time histories of wind turbine blades below flutter speed and captures the transient response in gusty and turbulent winds. The rational function coefficients and buffeting indicial function coefficients that appear in the time domain formulation were previously extracted for the NREL S830 airfoil, a low-noise and high lift to drag ratio airfoil with 21% thickness to chord ratio used in wind turbine blades, using section model tests in a wind tunnel. The objective of the current study is to evaluate how well these experimentally extracted coefficients can predict the aerodynamic loads on a blade in different wind conditions, through a separate set of tests conducted on a much larger (3.3 times) section model of the blade in a larger wind tunnel than originally used. The tests were performed for different upstream wind conditions (stationary, ramp-down gust, low turbulence and high turbulence) and the loads (lift and moment) were validated by simulating them in time domain using the measured displacements and comparing them with the measured ones. The amplitudes and pattern of the simulated aerodynamic loads compared reasonably well with those measured, even in gusty and more turbulent wind environment. | |||||||||
