Análise do escoamento sobre um aerofólio altamente cambrado em baixo Reynolds

Abstract

This work investigates the aerodynamic behavior of a highly cambered airfoil (E95) operating at low Reynolds number conditions. Three different approaches were employed: wind tunnel experiments, CFD simulations, and potential flow analysis using XFOIL. The objective was to analyze the lift polar and surface pressure distribution over the profile, enabling comparison and validation between the methods. The results revealed overall consistency, highlighting the presence of laminar separation bubbles and two suction peaks on the upper surface, especially well captured by CFD. Despite localized discrepancies, all methods complemented each other and reinforced the complexity of flow in low Reynolds regimes. This study contributes to the understanding of high-cambered airfoils and their use in lightweight aircraft, UAVs, and aerodynamic systems under critical performance demands.
