摘要

室内空气状况因其直接关系到人体健康而受到人们的重视。计算流体力学(CFD)仿真在建筑通风系统设计中有着广泛的应用。本文采用商用仿真软件Ansys对室内空气粉尘贡献进行预测。以大学生宿舍楼为模型，利用CFD模拟了宿舍楼内的风速分布和风道，预测了宿舍楼内的粉尘分布。同时，本研究通过粉尘传感器检测同一房间内的粉尘浓度。综合模拟和粉尘传感器的结果，得出了室内粉尘颗粒的分布情况。本研究将传感器网络与模拟相结合，可以计算具有边界范围的空气粉尘分布。在未来，该系统可以通过应用不同的传感器来预测导致空气污染的各种空气颗粒。

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.
