Title: RADIAL COMBUSTION DYNAMICS IN Fe[sub 2]O[sub 3]∕Al THERMITE: VARIABILITY OF THE FLAME PROPAGATION PROFILES
Abstract: In this work, the radial combustion in thin circular samples of stoichiometric and over aluminized Fe2O3/Al mixtures is studied. Two confinement materials are tested: stainless steel and PVC. The combustion front profiles are registered by digital video‐crono‐photography. The radial geometry allows an easy detection of sample heterogeneities, via the circularity distortions of the combustion front profiles. The influence of the Al content in the mixtures and the type of confinement on the combustion propagation dynamics is analyzed. Additionally, an asymmetry parameter of the combustion front profiles is defined and statistically treated via ANOVA. Although the type of confinement contributes more than the mixture composition to the variability of the asymmetry parameter, they both have a weak influence. The main source of variability is the intrinsic variations of the samples, which are due to their heterogeneous character.
