Abstract

This work introduces an easy-to-implement yet accurate method to model the temperature evolution of isolated iron microparticles during reactive cooling. The model is validated using state-of-the-art experimental data under multiple conditions. Because of its simplicity, this approach is poised for widespread adoption in large-scale iron dust flame modeling.

Novelty and significance statement

A novel approach is developed to model the reactive cooling of an isolated iron microparticle, which is validated using the experimental time history of particle temperature under different conditions. This method is more intuitive, accessible, and easier to implement compared to existing techniques. It significantly simplifies the modeling of iron particle combustion, enabling more efficient numerical simulations of iron dust flames.
