Overview

Comparative analysis evaluates airfoil performance in small-scale wind turbines, suggesting optimal choices for urban settings.

Key Points

  • 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.
