Multiple scales analysis on nonlinear pressure waves of a short wavelength in bubbly liquids with an initial polydispersity

Numerical investigation of the translational motion of bubbles: The comparison of capabilities of the time-resolved and the time-averaged methods

“…As the bubbles behave as mechanical oscillators, wave dispersion is expected. The increasing void fraction in bubbly media changes the acoustic properties of the liquid, such as the speed of sound and the nonlinear attenuation [31] , [55] , [56] , [57] , [58] . For close bubbles, the effect of bubble–bubble interaction is not negligible.…”
