An Indoor Airflow Simulation and Airborne Dust Concentration Analysis

Indoor air condition is paid attention by people because of its direct relation to human health. The Computational Fluid Dynamics (CFD) simulation is broadly used in architectural ventilating system design. Here, the commercial simulation software Ansys is used to predict the indoor airborne dust contribution. Based on a model of college students' dormitory, the CFD simulated air velocity distribution and air flow duct to predict the airborne dust distribution. Meanwhile, this study examined the dust concentration in the same room via the dust sensor. Integrating results from both the simulation and the dust sensor, we concluded the distribution of dust particles in the room. This study integrates the sensor network with simulation, allowing for computing the airborne dust distribution with a border range. In the future the system could predict a variety of airborne particles contributing to the air pollution by applying different sensors.
