Abstract
A stochastic model is proposed for modelling the turbulent dispersion of liquid fuel sprays. The approach adopted is based on the evolution equation for the joint probability density function (PDF) of the droplet properties. Turbulent dispersion is described by Langevin's equation in which a Weiner process is used to represent the stochastic force term. The method leads to plausible results when applied to a kerosene spray flame and provides a rational framework for the incorporation of liquid film break up and droplet formation processes.
