小径円管内に形成されるキャビテーションジェットの特性

抄録

Cavitation jet is one of the way to improve the processing performance of water jet. Cavitation jet emits ultrasonic sound, and its sound pressure is known to increase the effect of cutting or washing processing. The purpose of this study is to increase the sound pressure by using a narrow tube attached to the front of the nozzle. As a result, we clarified the conditions that the sound pressure becomes larger than in the case of without a tube.
