WebSeveral microbubble scattering models are highlighted (including the Rayleigh-Plesset model, the Rayleigh-Plesset-Noltingk-Neppiras-Poritsky model, the Herring model, the Marmottant model, and the non-spherical bubble dynamics model). The interaction between two microbubbles and the effect of radiation on the microbubbles is also discussed. WebDec 21, 2024 · The Rayleigh Plesset equation is a non-linear ODE, which can be solved to find the Radius of a bubble subject to non-linear oscillations due to an external driving sound wave (Sonoluminescence). Here is the form of the equation I used: Here is the python code I have written. It plots both the radius of the bubble and its radial velocity.
