Model for a Fluid-Particle Breakup in a Turbulent Flow.
Original language description
A model is developed for predicting the outcome of breakup of a fluid particle (bubble or drop), which is initially deformed (e.g. due to turbulence) and breaks into two daughter particles. An initially dumbbell-shaped deformation of the particle is assumed. The evolution of sizes of particle sub-parts is calculated using Rayleigh-Plesset equations, which consider the inertia of surrounding fluid, capillary action and viscous effects. The redistribution of internal fluid in the particle is calculated using Bernoulli equation. The model computes the sizes of daughter particles after the breakup. By assuming various initial conditions (various initial shapes and initial velocities of deformation), the size distribution of daughter particles is obtained. These size distributions are qualitatively compared with available experimental data and reasonable agreement is observed. Because of strong assumptions, this model cannot be used directly for accurate prediction of size distribution after a breakup. However, it provides an insight in the physics of the breakup, especially on the effect of inner phase properties.
