Abstract
The paper is devoted to numerical investigations of processes accompanying an underwater explosion near the free surface. A model of evolution of liquid and gas separated by free surface is implemented. The model enables one to take into account cavitation in rarefaction waves propagating through the liquid. Thus, the study is directed at phenomena of propagation of compression and rarefaction waves in the liquid and in the gas, of interaction of the waves with each other and with moving free surface, and of cavitation due to pressure drop in the liquid. Governing equations are solved by a numerical method based on Godunov-type high resolution scheme. Location of the free surface is determined utilizing information on distribution of the liquid volume fraction taking into account compressibility of both media. Computations of underwater explosion near the free surface have demonstrated robustness of the proposed algorithm.
