..., especially at small attack angles of a hydrofoil. In the present investigation, a turbulent viscosity correction model is proposed to dampen the turbulent viscosity at the water–vapor interface. Cavitation flow around a NACA0009 truncated hydrofoil with a 2.5 deg angle of attack is used to demonstrate...

.... The nearby solid wall has a significant influence on the added mass and hydrodynamic damping characteristics of a submerged structure. In particular, in the case of a hydrofoil, both the added mass and hydrodynamic ratio decreased, as the tip clearance increased [ 3 , 9 ]. As for the various side clearances...

... stiffness, and hydrodynamic damping ratio, in relation to the first-order bending mode of a vibrating hydrofoil. The investigated relative tip clearance ranges from 0.067% to 2% of the span length. The predicted vortex shedding frequency, natural frequency, and hydrodynamic damping ratio of the hydrofoil...

... for all foils. Thus, the effect of foil geometry appears only in the strength of partial cavity oscillation. Sato , K. , Tanada , M. , Monden , S. , and Tsujimoto , Y. , 2002 , “ Observation of Oscillating Cavitation on a Flat Plate Hydrofoil ,” JSME Int. J., Ser. B 1340-8054...
