Insights into the aerodynamic response of a harmonic oscillating airfoil in various turbulent flows.

ABSTRACT: The general theory of aerodynamic instability and the mechanism of flutter has been applied for decades in the environmental condition of uniform flow. Given the substantial growth in wind energy technology and aerospace in recent decades, there has been a greater focus on exploring the aerodynamic performance of oscillating airfoils in the environment of turbulence rather than just uniform flow. Most current research remains based on aerodynamic models obtained from potential flow theory, which have been thoroughly demonstrated through experimentation to be effective under the condition of uniform flow. However, it is still unclear whether turbulence and its interaction with the airfoil will cause traditional aerodynamic models to breakdown and how it will change under turbulent condition
