摘要	Ignition and combustion of Aluminum nanoparticles (ANPs) under complex environments are of great signifi cance for various propulsion systems. In this study, we investigated the oxidation process of ANPs in O2, CO2, H2O, and their mixture atmospheres using reactive molecular dynamics. In the mixture atmospheres, ANPs experience a shorter ignition delay and parts of C and H atoms are involved in a new reaction named re oxidation, where the nonbonded C and H inside ANPs detach from particle and re bond with free O in the environment to produce extra CO and H2O. It reduces C and H in unreactive diffusion and increases O in reactive diffusion. Additionally, it is found that the ignition delay time and reaction heat release can be adjusted to achieve the optimal performance of ANPs combustion by tailoring the contents of O2, CO2, and H2O in the environment. Our works provide a theoretical basis for the precise regulation of ANPs energy release.
