Rayleigh plesset方程推导

WebApr 13, 2024 · Previous works have proposed several analytical methods to understand the dynamics of spherical bubbles [9,10,11,12,13], such as the Rayleigh–Plesset equation [9,11] and the Keller equation . Prosperetti and Lezzi [13,14] derived the one-parameter family equation of the first and second-order Mach number, respectively. WebThe cavitation models are based on the Rayleigh-Plesset equation, describing the growth of a single vapor bubble in a liquid. In the Singhal et al. model, noncondensable gases have been introduced into the system. The mass fraction of the noncondensable gases is assumed to be a known constant.
