E.Yu.Rozina On the nature of the force acting on the cavitating medium near the end cross-section of the capillary |
Acoustic bulletin, Vol. 6 ¹ 3, (2003) |
| A dependence of sonocapillary pressure from the inner diameter of the capillary is experimentally investigated. It is shown that for small capillaries the sonocapillary pressure can sufficiently exceed the amplitude of the sound wave. It is also shown that power density in a cavitating liquid can several orders exceed the power density of exiting acoustic field. The sonocapillary pressure is interpreted as a result of action of steady force on the compact group of cavities in the direction of the fastest decrease of the amplitude of sound. |
