OPERATING CHARACTERISTICS OF THE LAUTERBACH AND DAUTREBANDE AEROSOL GENERATORS

摘要

The operating characteristics of the Lauterbach and Dautrebande aerosol generators have been studied. The output, in terms of micro¬liters of solution aerosolized per liter of air passing through the jet, was not appreciably affected by either the diameter of the jet orifice or the concentration of the solution. The output increased with increasing pres¬sure drop, ΔP, across the jet orifice, approaching an asymptote appar¬ently negligibly greater than the output at ΔP= 50 psi. The median diam¬eters of the particle size distributions were unaffected by either orifice diameter or jet pressure. They varied with solution concentration but to a lesser extent than had been expected. Mass median diameters, how¬ever, showed an effect of jet pressure as well as solution concentration.
