Abstract
Sources contributing to the acoustic nonlinearity of a gas/liquid mixture are discussed and calculations of a coefficient βeff for the second-order nonlinearity of the mixture are performed based on source strength density functions for parametric acoustic arrays and on formation with source distance of the second harmonic to a monochromatic wave propagating through the mixture. Some procedures for experimental determination of βeff are suggested, and it is concluded on basis of the calculations that the dynamic bubble nonlinearity will yield the predominant contribution to the acoustic nonlinearity of the mixture, in particular at resonance.
