Cavitation Performance of Cylindrical Choke. Critical Cavitation Number in unsteady Flow.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 This paper deals with an experimental study on the unsteady performance in the cylindrical choke of the oil hydraulic. Experiments are carried out under an unsteady flow in which the outlet pressure p2 of the cylindrical choke takes the form of a trapezoid varying with time, keeping the inlet pressure p1 constant. It is found that as the absolute value

Similarity Law on Shedding Frequency of Cavitation Cloud Induced by a Cavitating Jet
Journal of Fluid Science and Technology, 2012 In order to clarify the mechanism of cavitation cloud shedding, the shedding frequencies of cavitation clouds were investigated by high-speed observations and image analysis. The results indicate that the shedding frequency follows the similarity law for
