On the existence of stationary solitary waves in a dissipative bubbly liquid

The formation of a solitary wave during the propagation of acoustic perturbations in a liquid containing heat-conducting gas bubbles is revealed for the first time by means of numerical modeling. A physical mechanism explaining the existence of a nondecaying solitary wave in this dissipative medium is proposed, which is based on the reverse influence of the bubble motion dynamics on the heat balance between gas and liquid. This phenomenon is called the moving boundary effect.
