Abstract

In order to improve the reliability of high-speed hydraulic machinery, detailed behavior of the violent vibrations appearing on a typically low-drag Eppler foil is systematically observed by means of high-speed stereophotography. We can clearly observe the following three types of violent vibrations: (i) the vibrations resulting from a singly-attached cavity, usually arising at a higher incidence αi, (ii) ones resulting from large travelling bubbles arising at a lower incidence, (iii) a mixture of these two types.
