This study examines the aerodynamic features of oscillating and deforming airfoils with vertical axis wind turbine applications. An in-house large eddy simulation (LES) computational fluid dynamic code with the wall-adapting local eddy viscosity sub-grid scale model is used to perform simulations, first to replicate the results of a water tunnel experiment studying an oscillating airfoil, and second to analyze the effects of airfoil deformation on aerodynamic properties.

The main features shown in the water tunnel experiments at a Reynolds number of 10,000 are present in the results of the simulations, including separation bubbles and laminar to turbulent transition, showing the effectiveness of using LES to simulate dynamic stall.

The deformation of the airfoil's trailing edge is implemented using a spring-based mesh deformation method, showing the effects of this movement on the airfoil's pressure coefficient.
