Rayleigh-plesset方程的推导
WebRayleigh−Plesset Gilmore Figure 2: Comparison of predicted temporal variation of bubble radius from Rayleigh-Plesset and Gilmore equations for an ini-tial pressure and radius of … Webcussed Rayleigh-like and oscillatory bubble dynamics in N dimensions but only focused on the three-dimensional case and presented inconsistent results [1]. In this paper, the dynamics of a hyperspherical bubble are analyzed. Relevant terms such as the Rayleigh col-lapse time, Rayleigh-Plesset equation, and the Minnaert frequency are derived.
