摘要
利用CFX-10.0软件对通风房间三种不同工况进行了数值模拟,得到实验小室的速度场和浓度场。将模拟计算结果和实验数值进行了对比,较直观地反映了可吸入颗粒物的浓度变化。同时模拟了通风房间污染源的散发过程,并对典型的工况和在不同工况下的流场对浓度场的影响进行了分析。结果表明,CFX-10.0软件计算房间的污染物分布可靠性高,可用于评价室内的空气品质,同时对室内污染的控制策略提供依据。
Three different conditions in ventilated room are simulated by CFX-10.0. After the velocity-field and concentration-field in experimental cabinet is derived, the compare is done between simulation＇s results and experimental results. The emission＇s process of contamination sources in given cabinet is also simulated. The variations of concentration of inhalable particulate matter is visualized described. The relationship between velocity-filed and concentration-filed is analyzed. It is concluded that CFX-10.0 has sufficient reliability, which is used to estimate the indoor air qualities and provide references for indoor air contamination control.
