英文摘要	In order to study the influence of the factors on the accuracy of PM2.5 monitoring, including the sampling flow rate, particulate matter size distribution and number concentration, a simulated model for air-borne particulates is proposed in this paper. A cylindrical mixing tank with a Mini-Vol Sampler is chosen, the diameter of the tank is 240 mm and the height is 369 mm, the computational fluid dynamics (CFD) and or-thogonal test methods are adopted, the air continuous phase is calculated and the moving trajectories of air-borne particulates are simulated by adding discrete phase. The results show that the particulate matter number concentration has a relatively minor effect on the sampling efficiency, and the variances of both PM2.5 and PM10 sampling efficiency data are less than 0.3. The sampling efficiency of PM2.5 sampler is influenced both by sampling flow rate and particulate matter size distribution, and the measured accuracy can be improved when the sampling flow rate is 4 L/min.
