Abstract

This study presents simulation works carried out regarding to the airflow movement and particle dispersion in mechanically ventilated laboratory space at Faculty of Civil and Environmental Engineering of Universiti Tun Hussein Onn Malaysia. The measurement of air velocity was taken using Anemometer kit 4 in 1 while the particle dispersion was measured using Met-One Particle Counter GT-521 and measured at random points. The measured air velocity and particle dispersion are then used as input in simulation work using Comsol Multiphysics software. The simulation results are validated with the measured value and found that the percentage differences are within 6 – 10 % which is accepted by many researchers.This study found that the amount of particle dispersion increased toward the corner of the space and concurrently with the airflow movement. This is indicates that the particle dispersion depends on the airflow movement.
