Discussion

This investigation updates aerodynamic modeling for wind turbine blades with bending deformation, indicating implications for design.

The modified vortex cylinder model accurately captures the aerodynamic effects of blade bending deformation.
The new model shows strong agreement with high-fidelity computational fluid dynamics methods.
Geometric changes and aerodynamic induction effects are identified as key bending-induced effects.
The VC-BD model balances fidelity and computational cost for early-stage design and aeroelastic analysis.

Huang et al. (2025) studied this question.
