AIRFLOW BEHAVIOR IN PARTICLE TRANSMISSION IN AN OFFICE BUILDING

This article is about a parametric study of inlet air supply position for identifying the effectiveness of airflow behaviour of a room to dilute indoor air particle. It was carried out using COMSOL Multiphysics software of modelling and simulation approach. In simulation stage, the first process was to simulate the airflow behavior and the second was to assess its behaviour to dilute indoor air particle. Results from the simulation indicated that effectiveness of airflow behaviour in diluting indoor air particle are affected by inlet air supply position, outlet position and barrier condition in the room. Thus, these indicate that to improve IAQ of a room it needs to properly understand the airflow behaviour
