Leading-Edge Tubercles for Separation Control on Airfoils with Large-Amplitude Pitch Oscillations
Abstract
This report presents the findings of a comprehensive experimental study to investigate the impact of leading-edge tubercles on the aerodynamic behavior of airfoils. The study included force measurements, pressure measurements, and Particle Image Velocimetry (PIV). The airfoil models, with varying numbers of leading-edge tubercles, were tested across different angles of attack and Reynolds numbers to gain a comprehensive understanding of their aerodynamic behavior in both pre-stall and post-stall regimes. This report presents a detailed analysis of the lift and drag characteristics of the airfoil models with leading-edge tubercles compared to a baseline NACA 0010 airfoil profile. Additionally, the influence of the number of tubercles (wavelength) on the aerodynamic performance and its correlation with the angle of attack and Reynolds number are explored.
