Discrete Element Method (DEM) simulations are a promising approach to accurately predict agglomeration and deposition of micron-sized adhesive particles. However, the mechanistic models in DEM combined with high particle stiffness for most common mat

In this work, a mechanistic ash particle sticking and rebound criterion is developed and validated against experimental data. The model is able to predict the threshold of particle sticking and rebound as a function of the particle kinetic energy. Fu
The present work provides experimental results on structural changes of burning char particles derived in an entrained flow reactor. Changes in the char particle diameter, apparent and true density, specific surface area, and porosity are studied at
