Wind energy harvesting devices represent a viable alternative for obtaining energy and powering small low-consumption electronic devices. In the last work presented at MECOM 2023 was numerically analyzed the interaction between cylinder and airfoil immersed in an airflow using Ansys Fluent. The airfoil had mass and inertia properties adjusted to obtain the flutter condition, and it was linked to a fixed reference frame by means of springs. It was sought to quantify the aerodynamic interaction from the analysis of the power coefficient of the airfoil (dimensionless power, extracted from the air), based on the separation between cylinder and airfoil. In the present work, additional simulations were carried out to quantify the influence of other vortex shedding frequencies in the power coefficient of the airfoil. The results are analyzed and compared with results found in the bibliography.
