Resumen: | In the framework of applications of power ultrasound in liquid, this paper deals with the analysis of nonlinear ultrasonic waves through a bubbly liquid. An open-field domain is assumed to contain a water and air-bubbles mixture. The presence of bubbles induces a strong nonlinear behaviour of the wave. A set of coupled differential equations is considered to model this phenomenon, and solved numerically. The effect of the bubble distribution on the nonlinearity of the acoustic field is analysed. | Descripción: | Ponencia presentada en el XIX Congreso Internacional de Acústica (ICA2007), Madrid, 2-7 Sep 2007.-- PACS: 43.25.Yw. | URI: | http://hdl.handle.net/10261/5299 |
