This study aims to evaluate the aerodynamic performance of different airfoil profiles for VAWTs at low wind speeds.
Comparative analysis of six airfoil profiles for small-scale vertical axis wind turbines.
Aerodynamic performance examined using DMST and LLFVW models in the QBlade framework.
Focus on conditions typical of urban environments with wind speeds between 2-8 m/s.
Airfoils designed for low Reynolds numbers enhance startup torque under weak inflow conditions.
Symmetric NACA airfoils achieve higher power coefficients at operational tip-speed ratios.
The LLFVW model shows better agreement with experimental data compared to the DMST model.

Bernal-Orozco et al. (2026) studied this question.
