摘　　要：为了能快速排出室内污染物,利用计算流体力学(CFD)中的Fluent6.2软件,模拟了两种气流组织形式分别在3种通风速度下室内气流组织的速度场和甲醛的浓度场分布。对得出的速度场和浓度场进行分析:每种气流组织形式的速度场和浓度场都有较好的耦合性;其中下侧进上出的通风方式能更好的排除污染物;另外,适当增大送风速度能更好的降低污染物浓度。In order to expel the pollutant more quickly, this artical simulated the velocity field and the concentration distribution of indoor formaldehyde of two ventilation patterns under three different velocities by using Fluent 6.2 of CFD. The velocity field and the distribution of the concentration of formaldehyde were analyzed. Every ventilation pattern＇ velocity field and concentration field were coupled well. The ventilation pattern of the intake on underside and the vent on the upside can expel the indoor pollutant more efficiently, and increasing of the velocity can reduce the concentration of formaldehyde.
