Sommario
Mediante l'usa di uno schema asintotico viene dedotta una equazione differenziale alle derivate parziali del quarto ordine, atta a descrivere l'evoluzione di un'onda non lineare propagantesi con la velocità del suono in un liquido con bolle. Tale equazione in particolare presenta delle non linearità anche nette derivate di ordine più elevato. Infine vengono discussi alcuni risultati numerici connessi con la ricerca di soluzioni del tipo onda stazionaria e con la relazione di dispersione.
Summary
Though the use of an asymptotic approach, it is deduced a fourth order partial differential equation governing the evolution of nonlinear (sound) wave propagation in bubbly liquids. Remarkably it involves also higher order nonlinear terms. Some results concerning the steady-state solution as well as the dispersion relation are obtained.
