Particle Growth Processes in Screening Smokes.
Abstract
Experimental and theoretical studies have been carried out on the growth of oil condensation aerosols of the type employed by the U.S. Army as screening smokes. Studies of the vapor pressures of the complex oils have been carried out and new methods and results have been obtained. An experimental system has been developed, a laminar coaxial jet, from the vapor of oil condensation aerosols. The growth processes, for complex oil mixtures, are found to lead to the appearance of bimodal number density functions whose development we have studied for the first time. A numerical model has been developed of the experimental laminar coaxial jet and used in a theoretical study of coagulation in the jet. (Author)
