Abstract

The research presents the numerical modeling findings of the secondary breakup of droplets of coal water slurries containing petrochemicals (CWSP). The modeling method of the secondary droplet breakup is based on the VOF method for interface resolution, LES model for describing turbulence, and the technology of adapted dynamic grids. We have established the droplet breakup modes depending on the Weber number varying from 7 to 212. We have also examined the structure of the flow behind droplets. We have tested the numerical method, and the results are in good agreement with the existing experiments.
