Pressure Characteristics and Cavitation on an Oscillating Hydrofoil
Journal of the Society of Naval Architects of Japan, 1972 Unsteady cavitation that results from the non-uniformity of the flow field renders evil influences on marine propellers. It has been a general experiment for the investigation on such problems to observe unsteady cavitation in a flow field analogous to a wake pattern.

Investigation of Cavitating Cascades [PDF]
, 1967 Experiments on cavitating and noncavitating cascades were carried out in a conventional water tunnel modified for this purpose. The comparison of the experimental results with theory, in both the fully wetted and fully cavitating conditions, was found to

Observations of Oscillating Cavitation on a Flat Plate Hydrofoil.
JSME International Journal Series B, 1999 An experimental investigation was made to clarify the characteristics of oscillating cavitation on a flat plate hydrofoil in a water tunnel. Dynamic the behavior of oscillating cavitation is discussed from the unsteady pressure measurements at the upstream of the blade and the visual observations of cavitation phenomena using high-speed video ...

Shock Wave Measurements in Cloud Cavitation [PDF]
, 1997 One of the most destructive (and noisy) forms of cavitation is that referred to as "cloud cavitation" because it involves a large collection of bubbles which behave as a coherent whole.
