The Effect of Nonlinearity on Acoustic Streaming in Cylindrical Cavities of Different Diameters

Acoustic streaming in vibrating cylindrical cavities of different diameters under isothermal boundary conditions is numerically investigated. Two vibration frequencies are considered at various vibration amplitudes. The influence of increasing nonlinearity of the process on the structure of acoustic streaming is determined. The dynamics of an increase in the acoustic streaming velocity with an increase in the vibration amplitude is shown. The vibration amplitudes at which shock waves are formed in the regime of steady-state oscillations are revealed.
