摘要：
The specific features of pressure wave dynamics in a fluid containing a bubble zone are considered. It is found that for nonlinear waves the shielding effect of the bubble zone, typical of acoustic waves, is less pronounced. In some cases, due to the nonlinear effects and the radial inertia of the bubbly fluid [1], the bubble zone may result in a certain increase in the original-signal amplitude. It is shown that when a bubble screen is located near a solid surface, by choosing an appropriate bubble radius and volume fraction, it is possible to achieve (i) the absence of a reflected signal and (ii) substantial damping of the wave action on the wall.
