Abstract

Dynamics of pressure waves in a flat channel with a sloping boundary between bubbly and pure liquids is investigated. It is shown that, at the boundary between water–air mixture and water, reflection of waves incident on the boundary from the side of air–water mixture is analogous to reflection from a rigid wall, which leads to interference of waves. It is found that, with an increase in the volume content of bubbles and decrease in the bubble radius, the maximum wall pressure amplitude of the resulting wave increases.
