Modeling the combustion of nano-sized aluminum particles

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

An unsteady numerical model has been developed for the burning event of a single nano-sized aluminum particle in oxygen. Assumptions of constant particle size and one-step kinetics were made in conjunction with the use of a 1-D spherical coordinate system. The diffusion rate of oxygen through the outer layer of the particle has been assumed to control the rate of combustion. A parametric study was conducted to investigate the burn time characteristics. The dependence of the particle burn times on the diameter is discussed. A range of oxygen diffusivity values are studied.
