The Probability Density Function (PDF) approach has proved very useful in studying the behavior of stochastic systems. Examples of its usage occur in the study of Brownian Motion e.g. Chandrasekhar (1943) and in the kinetic theory of gases e.g. Chapman & Cowling (1952). In more recent times it has been used extensively by Pope (1991) and others to model both turbulence and turbulent related phenomena such as combustion and atmospheric dispersion e.g. MacInnes & Bracco (1992). In this chapter we review how the PDF approach has been used to model particle transport in a fixed Eulerian frame of reference (one particle PDFs) and in the frame work of a moving particle where it describes the relative motion of particle pairs (two particles PDFs). In the one particle case it is influenced by the large scales of the turbulence and in the two particles case it is influenced by the small scales of the turbulence.
