The Physics of Sound Scattering From, and Attenuation Through, Compliant Bubbly Mixtures

Abstract

The goal of this research is to acquire a quantitative understanding, leading to predictive models, of the broader aspects of linear and nonlinear sound scattering, transmission and coherency in oceanic bubbly mixtures pertinent to the shallow-water acoustics. This includes a conceptual understanding of the role played by damping and stabilization mechanisms in bubble dynamics and longevity. Of particular interest is the delineation of different regimes of behavior as a function of frequency, size distribution, flow and volume fraction.
