A numerical model of the combustion of single lithium particles with CO2

摘要: Abstract A numerical model for the ignition and combustion of lithium particles ( d p  = 20–250 μm) in pure CO 2 atmosphere was developed implemented ANSYS Fluent’s “discrete phase model”. The is based on experimental findings gained a laminar flow reactor: experiments indicate two reaction mechanisms: An initial high temperature above gas-phase (>2500 K) with zone apart from particle surface (“stand-of flame”) followed by at lower (1500–1800 K). As kinetics only available reaction, theoretical approach established to calculate duration mass conversion reaction. complete includes inert heating, melting steps described enables calculation single or droplet lithium. results simulation were compared conducted reactor. show, predicted behavior good agreement results.
