The Preparation and Utilization of Metallic Aerosols for Filter Paper Testing

Deposition of Suspended Particles from Turbulent Gas Streams

“…In these experiments (2) three types of powders were used: two grades of iron powder (Antara Chemicals Division, General Dyestuff Corp.) with mass median diameters of approximately 3 and 5 microns, respectively, and a standard geometric deviation of about 1 Present address, Department of Chemical Engineering, Columbia University, New York, N. Y. 1.4 (7); an aluminum powder of approximately 5-micron mean diameter (Reynolds Metal Co.); and lycopodium spores (McKesson and Robbins Co.), which according to Gregory have a diameter of about 30 microns (4).…”

“…The mixing and distribution of liquid droplets in high velocity gas streams were studied by Longwell and Weiss (70). Only a few experiments have been reported on the important problem of deposition of droplets (7) and the formation of deposits of dust (77) from turbulent gas streams.…”
