APECSS: A software library for cavitation bubble dynamics and acoustic emissions

Abstract

The dynamics of cavitation bubbles and the acoustic emissions they produce are important in a broad range of engineering applications and natural phenomena, either because the strong energy focusing of the bubble collapse is to be avoided, as it may cause damage to surfaces, or to be exploited, such as in emerging medical applications. APECSS (Acoustic Pulse Emitted by Cavitation in Spherical Symmetry) is a software library to simulate the dynamic behavior and acoustic emissions of cavitation bubbles using an efficient state-of-the-art numerical framework. APECSS supports different Rayleigh-Plesset models for bubble dynamics in incompressible and compressible media with Newtonian or viscoelastic rheology, considering clean or coated bubbles. Acoustic emissions may be modeled under different modeling assumptions using a tailored Lagrangian wave tracking method, including the formation and attenuation of shock waves. APECSS can be extended easily to include custom functionality and may be incorporated into other software frameworks.
