Abstract: New calculations of the photophoretic force are presented for a spherical particle that may be coated with a volatile concentric spherical shell. The distribution of heat sources within the particle was obtained from an ...

Abstract: Collection efficiencies of falling water drops ranging from 0.094 to.O.254 cm in radius for silver chloride aerosol particles in nitrogen ranging from 0.15 to 0.6 ?m in radius have been measured. The drops accelerated for ...

Abstract: This experimental study of the collection efficiency of freely falling water drops for AgCl aerosol particles in nitrogen extends earlier work (Kerker and Hampl, 1974) to submillimeter drop radii. In this case it was not ...
