Abstract

A diffusion problem for a spherically symmetric gas bubble in a liquid in an isotropic acoustic field is considered. The problem is solved both for a single bubble and for a bubble in a monodisperse cluster. A numerical method for solving the diffusion problem is developed. For the oscillating part of the diffusion problem the numerical experiments have been carried out for different amplitudes of the external pressure. A comparison is made between the calculation results obtained by the approximation theory and the numerical method presented. The effect of taking into account the mass change on the bubble dynamics is studied. For extensive parametric research the algorithm is paralleled and the parallelization efficiency is evaluated.
