Abstract

A technique for computing strong compression of an axisymmetric gas bubble in a liquid by direct numerical simulation based on the equations of fluid dynamics is presented. This technique uses a scheme of the second-order accuracy in space and time for smooth solutions. Some results of numerical investigation of efficiency of this technique are given. It is established that this technique is much more effective than the classical first order accurate Godunov scheme widely known in the literature.
