Around 1990, it was believed that “cavities generated by ultrasound are spherical cavities. It was said that the cavities disappear under the pressure of the dense and rarefied waves of ultrasound, and at that time, the pressure waves of the surrounding liquid concentrate towards the center of the spherical cavity, causing high pressure and high…続きを読む
Today, we succeeded in developing a high amplitude and new type of diaphragm. The measured value of the new sound pressure meter exceeded 30 [V]. When an aluminum can touches the surface of the liquid, it splashes violently, and the worker’s clothing becomes soaked. Estimated cavity diameter (microvacuum nucleus group) 12 mmφ. cavity impact force…続きを読む
