Title: A Dust Wind Tunnel for Particulate Matter Sampling Studies
Abstract: A new wind tunnel has been designed, fabricated and evaluated for the study ofparticulate matter (PM) samplers. The air velocity of the wind tunnel ranges from 2 km/h to 24 km/h.The velocity is uniform within 10% of the mean. A new, low cost dust feeder system was designed,which is able to disperse dust into the wind tunnel over a wide range of concentrations (0.01 g/min100 g/min). A Generic Tee Plenum System (GTPS) was used to achieve good mixing of particles inorder to achieve uniform concentrations throughout the sampler test chamber. In the testing sectionof the wind tunnel, the particle concentration is uniform within 10% of the mean. In addition, a dustlosscollector was designed to recover >90% of the dust loss to the inner wall of samplers inlet. Thisnew wind tunnel satisfies USEPAs wind tunnel requirements for testing PM10 samplers.
