• Description:
  Practical aerosol sampling in workplaces and the atmospheric environment involves the use of devices of complex shape with entry orifices whose orientation with respect to the wind can range over the full 360 degrees. For such systems, simple models of aspiration efficiency like those developed for thin-walled samplers are inadequate for describing sampling performance. Models based on considerations of the flow about bluff bodies with aspiration have enabled progress to be made, both in semi-empirical modelling and in numerical simulations (as reviewed by Vincent, 1989 and 1995). However, further progress requires new experimental data by reference to which improved models can be developed. [Description provided by NIOSH]
