Abstract
Experimental and theoretical investigation of an influence of the local layer parameters, presence of rigid boundary on the bubble dynamics under the action of strong pressure pulse as well as the formation of reflected signal are reported. It is shown that duration of reflected pulse, its amplitude and presence of an oscillations behing it depend not only on the amplitude and duration of incident pulse, but on the spatial gradient of void fraction and distribution of the bubble radii within the layer. This phenomenon is described within the framework of the model, taking into account a specific variation of void fraction inside the layer as well as the specific bubble dynamics in it.
