Particle Dispersion in Inhomogeneous Turbulent Flow

Abstract

A DNS code based on a spectral-element method is developed. The code is applied to calculate Eulerian space-time velocity correlation functions and to study the possibility to describe the dispersion of particles by a Langevin equation for particle velocity. The preliminary results indicate that it is possible to derive the damping coefficients from the correlation functions.
