Bubble dynamics in a fluctuating pressure field of a turbulent flow is considered. A computational model is formulated in the probability density function (PDF) approach. Growth or collapse of vapour bubble, initially at equilibrium, is described using the classical Rayleigh-Plesset equation. The input pressure surrounding the bubble is modelled by a stochastic differential equation of the diffusion type. Changes of bubble radius in time are computed and statistics are obtained for an ensemble of independent realisations. Presented results include the temporal evolution of the bubble radius probability distribution and the probability of cavitation inception as a function of bubble initial radius and pressure characteristics.
