CAVITATION EVALUATION DEVICE AND CAVITATION EVALUATION METHOD USING THE SAME

Japanese Patent JP2010019644

A

To provide a cavitation evaluation device for detecting only vibration caused by cavitation occurring in liquid for evaluation, and to provide a cavitation evaluation method using the cavitation evaluation device.

The cavitation evaluation device 10 includes: a liquid pressure generator 1 for applying pressure to liquid for sending out; a first channel for passing the liquid that has been sent out; a second channel 3 that communicates with the first channel 2 and includes a channel sectional area narrower than the first channel 2; a third channel 4 that communicates with the second channel 3 and includes a channel sectional area wider than the second channel 3; and a vibration detection means 5 that is mounted to the third channel 4 and detects vibration generated in the third channel 4.
