Immersed-boundary time-domain simulation of acoustic pulse scattering from a single or multiple gas bubble(s) of various shapes

Acoustic scattering and resonances resulting from a point pulse on a single or multiple gas bubbles are simulated using a time-domain simulation. The time histories of scattering pressure and velocity, both outside and inside the bubbles, are obtained simultaneously with an immersed-boundary method...

Description
Summary:Acoustic scattering and resonances resulting from a point pulse on a single or multiple gas bubbles are simulated using a time-domain simulation. The time histories of scattering pressure and velocity, both outside and inside the bubbles, are obtained simultaneously with an immersed-boundary method implementation. The acoustic resonances of the bubbles are investigated for various bubble numbers, sizes, shapes and interior gas parameters. For several cases, the scattering and resonance behaviors are compared with the existing theoretical and experimental results.
