INFLUENCE OF WAVY SURFACE TO BOUNDARY LAYER STRUCTURE AND AERODYNAMIC PERFORMANCE OF FINITE SPAN WING
The material was received by the Editorial Board: 18.04.2011
Investigation of small size aircraft wing was performed. Two wing models had same airfoil, but the first model had a smooth surface and second one had a wavy surface. Significant difference between aerodynamic performances of two wing model was found. Key features of boundary layer at various angles of attack were revealed by oil-film and thermovision visualization methods. These features are a reason to aerodynamic performance difference. Keywords:
low Reynolds number, wing aerodynamic performance, boundary layer, separation bubble, transition, oilfilm visualization, thermal imager.
