This manuscript deals with the combustion of nanothermites in a closed volume. A firststudy was focused on the combustion of aluminium particles with gaseous oxygen. Afterdetailed the reaction mechanisms implemented, the numerical integration of a combustioncode on PYTHON was done. To observe the main condensed and gaseous behaviors, afirst c...

Reactive materials or nanothermites are composites or physical mixtures that demonstrate selfsustaining exothermic reactions upon receiving an initial energy input. This category of materials is distinctive within the realm of energetic materials, differing from explosives in the manner in which reaction fronts propagate subsonically and rely...

Nanothermites are interesting energetic systems as their combustion driven by the oxidation of the metallic fuel associated with the reduction of the oxidizer, can produce extremely fast burning rates exceeding hundreds of m.s-1. In addition, by changing the reactant (composition, stoichiometry) geometry and compaction conditions, the control...

Mixtures of metal/metal-oxide, commonly known as thermite, can burn in a self-sustained reaction with an ultra-high energy density [1-2]. The high combustion temperature, safety, and tunability of thermites make it possible to produce totally novel pyrotechnical devices for inspace maneuvers (stage separation, pulse power generation for...

The paper is a theoretical exploration of complex Al/CuO thermite combustion processes, using a zero-dimensional (0D) model which integrates both condensed phase and gas phase reactions, and considers all thermodynamic stable molecular or atomic species identified during the Al+CuO reaction. We found that the particle size mainly influences the...
