Introduction

The paper is devoted to numerical simulation of processes accompanying underwater explosion near the free surface. In spite of the fact that the problem has been attracting attention of many researchers (see, for example, [1, 2, 3]) challenging problems still remain. The main attention in this paper is paid to compressible and rarefaction wave propagation, to their interaction with each other and with the liquid-gas interface, to deformation of the free surface.

Analysis of these phenomena is important for both progress of theory of heterogeneous media and applications utilizing specific features of underwater explosions. One of goals of this study is development of efficient, convenient, and flexible tool for investigations of such phenomena.
