We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Stemphanie,

If your coal particle has water content/moisture - then latent heat needed for evaporation of water will be specified under water droplet material. The energy releases as part of the volatile reaction is based on the heat of combustion based on the volumetric reaction of volatiles. The latent heat specified under combusting particle corresponds to the heat utilized to release the volatile vapor. The details can be referred in section "12.16.3 Heat Exchange" in Fluent Theory Guide (23R2 document). Also refer table 23.3 in 23R2 Fluent User Guide (which specify the property inputs for combusting particle obeying laws 1-4).
