Interfacial wave dynamics of a drop with an embedded bubble
Physical review. E
This article describes how an embedded bubble changes the surface wave of a suspended liquid drop, and how such modifications, if recorded experimentally, can be used to detect voids in typically opaque interior of the fluid. The analysis uses a matrix formalism to predict the frequencies for natural oscillation and the deformation for acoustically induced forced vibration. The theory shows that the embedded cavity causes major shifts in the frequency and amplitude values as well as twofolddoi:10.1103/physreve.93.023119 pmid:26986425 fatcat:uwokhayaqjc4hacnifyue4zimu
