Abstract
This paper deals with an experimental study on the flow visualization of cavitation for steady and unsteady flows in cylindrical chokes of oil hydraulics. Experiments for the unsteady flow are carried out under a condition in which the inlet pressure p1 in the cylindrical choke takes a trapezoided form with time, while keeping the outlet pressure p2 constant. The behavior of the cavitation bubbles is clarified with an ultrahigh-speed camera under two geometric parameters: the diameter and the chamfered length of the choke. Also, a method for suppressing the occurrence of cavitation is studied. It becomes clear that a bubble which appears in the earliest stage of cavitation "grows, collapses, disappears and reappears repeatedly" at intervals of about 1.0x10-4 seconds.
