Abstract

Numerical simulation was used to study the dynamics and acoustics of a cloud of cavitating bubbles. The simulations employed fully non-linear, non-barotropic, homogeneous flow equations coupled with the Rayleigh-Plesset dynamics for individual bubbles. The computational results confirmed that an inwardly propagating shock wave may be formed in the collapse of a cavitating cloud. Major parameters that affects the far field acoustic noise produced by the volumetric acceleration of the cloud were examined. The non-dimensional far-field acoustic impulse produced by the cloud collapse is shown to depend, primarily on the maximum total volume of the bubbles in the cloud normalized by the length scale of the low pressure perturbation.
