Numerical simulation of WCF droplets trajectories using Ansys Fluent
The results of numerical simulation using Ansys Fluent software of the droplets trajectories formed during the atomization of water-coal fuel (WCF) using pneumatic mechanical nozzles are presented. The trajectories of two qualitatively different systems are modeled: coal “particle droplets” and water-coal droplets. It is found that the trajectories of moving “particle droplets” and WCF droplets in the vortex chamber have the form of spirals, while the residence time of burning “particle droplets” and WCF droplets in the furnace is proportional to their diameter, which makes it possible to ensure their near-complete burnout.
