A Thermal Fragmentation Model Induced by Surface Solidification

Abstract

A fragmentation phenomenon of a melt droplet induced by surface solidification has been studied for many years, but the fragmentation rate model, based on such a thermal mechanism, is not available for numerical simulation tools. In this study, in order to develop a fragmentation rate correlation of a melt droplet, induced by surface solidification, a thermal fragmentation mechanism is proposed, based on the Taylor instability. The theoretical fragmentation model is developed and a simplified non-dimensional correlation is proposed for convenient application to simulation tools. The developed fragmentation rate correlation is verified by simulating the MIXA experiment.
