Thickness effect of NACA symmetric hydrofoils on hydrodynamic behavior and boundary layer states
Résumé
The present study investigates experimentally the hydrodynamic behavior of 2D NACA (15%, 25%, 35%) symmetric hydrofoils at Reynolds number range 0.5 ∙ 105 to 1.3 ∙ 106. A particular attention is paid on the hysteretic behavior at static stall angle and a detailed cartography of boundary layer structures (integral quantities and velocity profiles) is given in order to put in evidence the mechanism of the detachment and the onset of von Karman instability.
