抄録

Simultaneous measurements of a bubble collapsing behavior and a bubble impulsive force were conducted near a solid wall behind a circular cylinder. The appearance of a bubble was recorded using a high-speed video camera. The impulsive force was measured with a pressure sensor made of piezo-ceramics. As a result, it was found that the bubble collapsing behavior has three patterns. The first pattern is a quasi-spherical bubble collapse at a distance from the solid wall. The second one is a bubble collapse accompanied by a severe impinging motion toward the solid wall. The third one is a bubble collapse in which the bubble does not lose its long shape. According to some discussions, the second pattern has an intense impulsive force and provides experimental evidence of the existence of high speed flow toward the wall. Hence, this impinging collapse pattern of a cavitation bubble plays an important role in a highly impulsive force, as well as the first pattern of a quasi spherical collapse.
