Abstract
This paper presents a quenching/sampling method for studying the evolution of monodisperse particles based on a comparison of the parameters of a set of particles before and after combustion. Burning 100-µm aluminum agglomerates were produced using inclusions of a metallized propellant in the form of ∅130 × 150 µm cylinders introduced into a nonmetallized propellant. In experiments with 100-µm aluminum particles, the latter were also introduced into the nonmetallized propellant. A description is given of the procedures employed in the particle-size and morphological analyses, particle density determination, and calculations the combustion time and the residence time in the flame.
