Bulk condensation in a dusty vapor–gas flow with regard to dust particle size distribution

Resumo

Bulk condensation in a dusty vapor–gas flow has been numerically simulated taking into account dust particle size distribution. Two types of distribution (monodisperse and lognormal) have been used. Changes in the bulk condensation process that are relevant to the dustiness of the flow have been revealed by comparing the results obtained for dust-free and dusty flows at the monodisperse dust distribution. Variations in the relative contributions of the homogeneous and heterogeneous mechanisms with variations in the flow dustiness have been considered. The effect of the root-mean-square deviation in the dust particle sizes on the bulk condensation in the dusty flow has been illustrated by comparing the data obtained for the monodisperse and lognormal distributions.
