Numerical modelling of nonlinear waves process in a liquid with bubble channel

Numerical modelling of pressure wave propagation is considered in a liquid with air bubbles, which are in the rectangular channel. It is assumed that the liquid is the acoustically compressible one and besides that the Herring-Flynn equation is used for the bubble description. It is shown that properties of the pressure wave propagation depend on the gas volume content and on the bubble area width. Regimes when amplitude of the pressure wave is much more than initial one are found. The structure wave in the bubble area is discussed. Regimes when the pressure splash exists in the bubble channel for a long time are found.
