This thesis presents the development and exploitation of a model that simulates both the initiation and propagation reaction of powder-based nanothermites with purely condensed phase mechanisms. Three main goals have been targeted: - A predictive model of both the initiation and propagation of the nanothermite reaction for powder-based systems...

A model based uniquely on condensed phase reactions coupled with the thermal equation is developed to study the initiation and early stage of the redox reaction in Al/CuO nanothermites. It considers the effect of a wetting contact angle between Al and CuO particles, which may be induced by sintering mechanisms and/or the synthesis method. In...

This paper describes a kinetic model dedicated to thermite nanopowder combustion,in which core equations are based on condensed phase mechanisms only. We explore all combinations of fuels/oxidizers, namely Al, Zr, B/CuO, Fe2O3, WO3, and Pb3O4, with 60 % of thetheoretical maximum density packing, at which condensed phase mechanisms govern the...
