AI Article Synopsis
- - A simplified model examines how sound waves scatter off a toroidal (doughnut-shaped) gas bubble in a compressible liquid.
- - The model assumes small volume oscillations of the bubble and that radiation damping is the main loss mechanism because of the bubble's size.
- - A formula for the scattering cross section of the bubble is developed and compared to detailed finite-element simulations of the complete scattering scenario.
Article Abstract
A simplified model is presented describing acoustic scattering from a toroidal gas bubble in a compressible liquid. It is assumed that the volume oscillations of the bubble are small enough that a linear approximation is appropriate, and furthermore, that the bubble is large enough that the dominant loss mechanism is radiation damping. An expression for the scattering cross section for such a bubble is derived, and the results are compared with finite-element calculations of the full fluid-fluid scattering problem.
