摘　　要：建立非简化的全自由尾涡模型,以精确计算尾涡对风力机气动特性的影响;应用经典的升力线理论建立叶片气动模型,以准确计及粘性效应;利用预估-校正-松弛策略以保证尾迹求解的稳定性。借助并行处理技术和快速多极子方法加速诱导速度计算,极大降低了全自由尾涡模型的计算成本消耗。最后以NREL实验风轮为算例,并与CFD计算结果进行对比,验证了该方法的有效性。With the aim of accurately taking into account viscous effects and profound influence of vortex sheet downstream on the aerodynamic performance of wind turbine blades, a model combing blade aerodynamic model based on the classic lifting-line theory with full free vortex wake model was presented, The numerical solution was insured to be fast and stable by parallel processing, fast multipole method（FMM） and predictor-corrector-relaxation scheme. The validity of present method were performed through comparisons with the National Renewable Energy Laboratory （NREL）experimental data and CFD results from the references, under axis flow and yaw condition, respectively.
