Aluminum combustion in CO2-CO-N2 mixtures

This paper considers a new experimental set-up to image and study the combustion of single burning aluminum droplet, which is levitated electrostatically. work focuses on CO2, CO mixtures thereof, that have not or scarcely been studied. Aluminum found burn in pure CO2 diffusion mode (with D01.9 scaling, where D0 initial particle diameter) whereas kinetically limited halts swiftly, irrespective pressure range 1–15 atm. Mixtures suggest major driving effect from compared CO. Overall, N2 behave as inert species. All time data are processed propose empirical correlation for CO2-CO-N2 significantly improves widely used Beckstead’s while including role N2.
