Overview

Numerical investigation reveals plasma actuators significantly improve lift and drag in heaving-pitching motions of an airfoil, indicating effective flow control methods.

Key Points

  • The aim is to assess the effect of plasma-based active flow control on the aerodynamic performance of a heaving-pitching airfoil.
  • Simulation using large eddy simulation (LES) turbulence method
  • Modeling a NACA 0015 airfoil under heave-pitch motions
  • Application of dielectric barrier discharge (DBD) plasma actuators with varying force intensities
  • Case-LF showed 1.46% improvement in lift coefficient (Clrms) and 14.57% reduction in drag coefficient (Cd)
  • Case-HF exhibited 11.65% lift increase, 19.87% drag reduction, and a 39.8% improvement in lift-to-drag ratio compared to baseline
  • Plasma application resulted in significant aerodynamic performance enhancement during complex motions.
