The acoustic scattering by a submerged, elastic spherical shell: High‐frequency limit

Scattering of Longitudinal Elastic Waves From an Anisotropic Spherical Shell

Calculation of the Transition Matrix for the Scattering of Acoustic Waves from a Thin Elastic Spherical Shell Using the Comsol

Acoustic Scattering Fromacoated Elastic Shell: Exact vs. Approximate Theory

The interaction of acoustic waves with fluid-loaded shell structures is an ongoing area of interest in underwater acoustics, ship construction and detection. The elasticity of the structure permits strong surfaceborne wave effects, which can be significant or dominant in large structures (many wavelengths in size). The significance of surface borne waves is compounded by low loss factors, enabl...

Acoustic Scattering by Shell-Covered Seafloors

Benthic shells are in the broad acoustic category of complex finite-sized shapes for which there is no exact mathematical solution to describe the acoustic scattering. Subsequently, the research program is a combination of theoretical analysis, numerical simulations, laboratory experimentation at WHOI, and comparison between models developed in this program and scattering data collected at sea....

Acoustic treaming visualization in elastic spherical cavities

Flow visualizations are presented for acoustic streaming occurring inside spherical elastic cavities oscillating in an acoustic field. Streaming flows are visualized using Particle Image Velocimetry (PIV) and results are observed for a range of values of a dimensionless frequency parameter, M =120-306. Over the frequency range investigated, streaming flow fields remain steady at a given value o...
