Abstract
This study deals with a random walk simulation of particle transport and deposition
from a stationary, isotropic turbulent flow: This is an inplernentation of the well-known Lagrangian approach. which treats the disperse phase as many particles. The trajectory
of each particle is calculated according to the equations of the mottion assuming a discrete
eddy-field.
The ensemble-ayeraged quantities describe the behavior of the particle-fluid system,
and these have been used to validate numerical solutions of a kinetic (probability density
function transport) equation which models the same system. In this work we have only
considered relatively large particles: particle-particle interactions and the influence of the
particle phase on fluid phase have been neglected
