A simple theoretical model is presented for the distribution of air speeds in a modified horizontal elutriator consisting of groups of plates with different lengths. Equations are presented for calculating the particle penetration both in channels of shortended plate lengths, as downstream the end of a shortended plate.
Keywords: aerosol dust elutriator preseparator sampling
