Comparison of three simulation methods of indoor particle dispersion

Numerically simulates the indoor particle dispersion in a threedimensional ventilated room by the Lagrangian model, the drift flux model and the passive transport scalar treatment method. Compares the simulation results with the previously published experiment data. The results show that the simulation results by the Lagrangian model agree well with the experiment data except in the area near the ceiling and air inlet, and that those by the drift flux model agree well with the experiment data near the ceiling and are slightly smaller than the experiment data at the other locations, and that those by the passive transport scalar treatment method agree well with the experiment data in the area below 0.3 m and have larger difference with the experimental data near the ceiling.
