Abstract

We have investigated how the accuracy of the Lagrangian particle modeling varies with the model parameters. Interactions of particles with turbulent airflow are simulated by solving the Reynolds-averaged Navier-Stokes (RANS) equation along with RNG k-e turbulence model. The model calculates trajectories of particles by equating particle inertial force to external forces acting on the particle including gravitational, drag, lift, Brownian, and thermophoretic force. We find that accurate velocity field, appropriate number of particle trajectories, modeling turbulent dispersion, and deposition treatment are very important to produce meaningful results.
