Rayleigh-plesset
WebQuadratic Pade approximants are used to obtain energy levels both for the anharmonic oscillator x2/2- lambda x4 and for the double well -x2/2+ lambda x4. In the first case, the complex-valued energy of the resonances is reproduced by summation of the real terms of the perturbation series. The second case is treated formally as an anharmonic oscillator … WebJul 10, 2024 · In this work, we consider the Rayleigh-Plesset (RP) equation for describing spherical gas-filled bubbles dynamics in N-dimensions. A new approach to construct analytical solution for the RP equation is proposed using trigonometric function. As its application, we study the adiabatic compressions by monatomic gas and diatomic gas.

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.
WebOct 22, 2014 · The Rayleigh-Plesset equation is usually derived by considering the dynamics of the bubble radius, R. This can be done in two basic ways: Differentiation with respect to R of the balance between the kinetic energy in the liquid and the potential energy in the gas; Integration of the Navier Stokes equation.
