The deposition of bacterial aerosol on a round-nose wedge in the interception region

The interception deposition on a round-nose wedge is investigated by the use of E. coli bacterial particles. These particles have a self-amplifying property when deposited on surfaces coated with nutrient material. Experimental data show good agreement with theoretical calculations based on boundary-layer theory. The technique is useful whenever the deposition efficiency or the available time for collecting particles on a surface is minimal, especially when the deposition surface is topographically complex.
