TL;DR: In this paper, the authors constructed a mathematical model that describes the interactions among droplets, dust and airflows in a fully-mechanized excavation face, and validated the accuracy of the established model.

TL;DR: In this paper, a CFD-DEM airflow-dust coupled simulation approach was developed based on k-e two-equation turbulent model and the Hertz-Mindlin model.

TL;DR: In this paper, a multiscale method was proposed to investigate the atomization characteristics of the pressure-swirl nozzle for dust reduction, which distinguishes between internal flow field, primary atomization and secondary atomization.

TL;DR: Based on the k-e two-equation turbulence model, Hertz-Mindlin model and the CFD-DEM coupled interface compiled with C++ language, the authors constructs a simulation model of the coupling between airflows and dust in a fully-mechanized excavation face, and then simulates the airflow fields and dust fields under forced/exhaust ventilation conditions with and without a novel air curtain generator being utilized.

TL;DR: Aiming at the problem that it is difficult to control high dust hazard in fully mechanized mining face with large mining height, an airflow-droplet coupled model was established based on the Euler-Lagrange method as discussed by the authors.
