WebThe Rayleigh–Plesset equation is derived from the Navier–Stokes equations under the assumption of spherical symmetry. [] Neglecting surface tension and viscosity, the equation was first derived by John … Webpressible. His work was extended by Plesset [16], who derived the second-order non-linear ordinary differential equation for the time-dependent bubble radius evolution, which became the well known Rayleigh–Plesset equation for bubble dynamics. Improve-ments of this equation have been proposed by numerous authors,
