Turbulent structure effects due to ordered surface roughness

The effects of ordered surface feature in the form of converging-diverging riblets are investigated experimentally on an airfoil. Riblet sheets are applied onto the surface of NACA 0026 airfoil at a yaw angle of α=0°,±10°, Riblet height of h = 1 mm, and riblet spacing of s = 2 mm. The length of the...
