Abstract
The results of a mesh analysis of aluminum powders are considered. It is shown that the particle mass distributions are nearly normal or lognormal. The differences in the combustion dynamics between powders consisting of polydisperse particles and particles of the same sizes are studied. It is established that these differences are manifested only in the late stage of combustion and are due to the presence of a coarse particle fraction in the powder.
