• Description:
  A theoretical model and computer program for predicting the sampling errors for various inlet geometries encountered in personal air sampling equipment were developed. The computer program was designed to accommodate various inlet geometries such as circular tube and parallel plates. Sampler devices with faces not perpendicular to the ambient flow could be simulated by a line sink. The theoretical model accounted for inertial and sedimentation effects on particle motion. The results obtained by use of the computer program system agreed well with experimental data found in the literature. The author concludes that the major difficulty in evaluating various inlet geometries is obtaining the flow around the sampler; however, an experimentally determined flow field and the particle motion part of the computer program can be used to accurately evaluate various inlets.
