文摘

A multiscale model for traveling bubble and sheet to cloud cavitation is presented. Tracking subgrid free nuclei and wall nucleation fully recovers sheet dynamics. The model is validated against experiments on 2D and 3D NACA0015 foils. Cavity length and period of oscillation match very well observations. The evolution of sheet cavitation on a 3D oscillating hydrofoil is simulated.
