Correlation between aerodynamic forces and vortex dynamics of a NACA0012 wing section in compressible dynamic stall via IDDES

Key Points

• Dynamic stall significantly alters aerodynamic forces acting on the NACA0012 wing section, elevating lift and drag fluctuations.
• Using implicit detached-eddy simulation (IDDES) reveals intricate vortex dynamics affecting airflow behavior near the wing.
• Numerical simulations demonstrate how compressible flow affects lift during dynamic stall, with implications for aircraft design.
• Understanding these interactions may enable improved performance predictions for aircraft under various flight conditions.
