Numerical Analysis of Combustion of a Single Aluminum Droplet in Water Vapor

Abstract

In this study, variable chemical kinetic mechanism between aluminum and water vapor were selected. Major species,which were produced by reaction with aluminum and water vapor,were compared with another reference as a result total 41 chemical kinetic mechanism and 19 species were validated. Aluminum droplet size is 230 μm and analyzed as 2-D axisymmetric model. As using Fluent 13.0, governing equations and species equation were solved onsurrounding aluminum droplet. The condensation/dissociation of alumina, that is the species of major aluminum oxide, were considered by including chemical kinetic mechanism
