NUMERICAL INVESTIGATION OF THE INFLUENCE OF HORN ICE FORMATION ON AIRFOILS AERODYNAMIC PERFORMANCES
Get access
ABSTRAKT
The numerical studies of the aerodynamic characteristics of the wing profile NACA 0012 with horn ice formations are presented. The results have been compared with the experimental data obtained within low-velocity wind tunnel AT-4 "KHAI." Both shape and roughness of the outgrowths corresponded to icing regimes typical for glaze ice formation. The studies were carried out within a wide range of attack angle α = −4°... 18° when the Reynolds number was Re = 0.67 × 106 and flow velocity was V∞ = 53 m/s. Effect of a flow-field structure on aerodynamic characteristics of the profile has been determined.
