long flexible blades
deep stall
叶片的高频振动,instability
SIV-1 stall induced vibration 攻角在-150-150,也会引起vibration SIV-2 ,存在两个问题 :1没有气动数据,没有unsteady 模型
IAG dynamic stall model
IAG在Cl Cd Cm上都更准确 13%,21%, 24%厚度
IEA 15MW DLC 6.3 BEM + no DS BEM + BL model 都出现叶片抖动 BEM + IAG model 不抖动,但是也出现停顿

flexible turbine assembly tree superelement ()
model imbalance
- add 模块之间的offset
better support of early blade design process independent meshes between aerodynamic and structure
基于api前处理和后处理
bladed 5 new features
-
yaw bear model
-
add sensors to simulation
