CFD-DEM simulation of copper droplet interactions during smelting

Novel method was created for simulating interactions of small droplets during copper smelting process. Two modelling methods were coupled to solve a common case and new submodels were created to simulate coalescing droplets and effect of reactions. With the simulations, a flow phenomenon was observed which highly increases settling rate of the droplets, and thus, is an important factor for limiting copper losses.
The method offers higher accuracy compared to more traditional CFD simulations as each droplet is individually simulated. As this increases needed computation power, the method is currently better suited to simulating smaller details instead of full-scale smelting process.
