  • MP-26 Nonlinear Dynamics and Bifurcation in Rayleigh-Plesset Equations for a Single Bubble Motion in Liquids

抄録

We show the variational formulation of the Rayleigh-Plesset equation for single bubble dynamics in static water by the Hamilton-Pontryagin principle. Then, we illustrate the bifurcation phenomena associated to an amplitude of the bubble radius response as to the amplitude of the input pressure under forced oscillating pressure at constant temperature. Lastly, we show that there exists a stable state of the amplitude of bubble radius under the forced pressure with higher frequencies.
