Aerodynamic behaviour of prismatic bodies with sharp and rounded edges

Aerodynamic behaviour of prismatic bodies with sharp and rounded edges The aerodynamic behaviour of prismatic bodies in a wide range of angles of attack is addressed in the present work. In particular, we focus on bodies with a basically rectangular shape, either sharp or cylindrical edges and different thicknesses. In general, the thinnest bodies exhibit the largest lift-to-drag ratio at moderate angles of attack, which is further enhanced with rounded edges. At larger angles of attack, bodies with rounded edges exhibit smaller drag than bodies with sharp edges. Roughness was found to enhance the lift-to-drag ratio significantly at small angles, and drag is reduced at larger angles. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

The aerodynamic behaviour of prismatic bodies in a wide range of angles of attack is addressed in the present work. In particular, we focus on bodies with a basically rectangular shape, either sharp or cylindrical edges and different thicknesses. In general, the thinnest bodies exhibit the largest lift-to-drag ratio at moderate angles of attack, which is further enhanced with rounded edges. At larger angles of attack, bodies with rounded edges exhibit smaller drag than bodies with sharp edges. Roughness was found to enhance the lift-to-drag ratio significantly at small angles, and drag is reduced at larger angles.
