Book Description
A laboratory method was developed for determining the droplet size distribution produced by atomizers. The atomizer is placed in a tube in which air is flowing at a velocity of 10 m/sec. The droplets flow downstream around a rod which has one flat surface covered with soot and a thin layer of magnesium. The rod is enclosed in a cylindrical shutter which can be rapidly opened to expose the soot-magnesium surface to the droplets which upon impact leave traces which can be studied microscopically. The instrument was tested with glycerine-water mixtures and an aerosol generator. The droplet distributions obtained were in good agreement with measurements made by two other methods.
