Abstract: The dynamics of inert and chemically reactive single bubbles in solitary waves of various intensities were calculated. Calculations of the dynamics of layers of reactive bubbles in the pressure field of solitary waves allows a description of the wave structure of bubble detonation. In the model proposed, the detonation wave is formed from the pressure pulsations resulting from the action of the averaged pressure field of the entire ensemble of bubbles on each individual bubble layer. Each bubble performs two to three oscillations, producing pressure pulsations in the liquid that exceed several times the amplitude of the averaged wave. The model with the discrete arrangement of bubbles has for the first time provided agreement between calculated and experimental profiles of the bubble detonation wave pressure.

Keywords: bubble detonation, solitary wave, soliton, bubble medium.
