Abstract

Flow detachment from lifted bodies like airfoils causes a remarkable decrease in
its aerodynamic performance. Therefore, the current work aims to recover the
performance by considering a fluidic oscillator device that adds momentum energy
near the separation zone to recover the separated boundary layer. Since the flow is
turbulent, RANS modeling was used, and the problem was simulated using
OpenFOAM software. Validation is an essential step to select the adequate turbulence
model to detect separation by comparing the results with experimental and numerical
published work. Actuation parameters were investigated to optimize the performance
