To facilitate improvement of the reliability of hydraulic machinery, detailed behavior of the violent vibrations is systematically observed by means of high-speed stereophotography for the Eppler hydrofoil. We can clearly observe the following three types of violent vibrations : (i) those resulting on a single attached cavity at a larger incidence αi, (ii) those resulting on large travelling bubbles at a small αi, (iii) the mixed type.
