Bubble collapse during cavitation serves as an e ective means of concentrating the di use energy of sound: compression of a gas generates heat. When the compression of bubbles occurs
WebJan 1, 2016 · An acoustic wave (a sound wave) is a propagation of pressure oscillation in the medium with the velocity of sound (Fig. 1) [ 1 ]. The sound velocity in liquid water is about 1500 m/s, while that in air is about 340 m/s. An acoustic wave (Reprinted with … WebCavitation is the sudden, unstable expansion of a void or bubble within a liquid or solid subjected to a negative hydrostatic stress. While predominantly studied in fluids, cavitation is also an origin of damage in soft materials, including biological tissues. Examples of cavitation in fluids and soft solids are shown in Fig. 1 A – C.
