Abstract
A theoretical simulation model of solid particles behaviour inside a scrubbing pool was developed, with the purpose to evaluate the particles decontamination factor. A three-step approach to describe pool scrubbing on the local instantaneous scale, using Computational Fluid Dynamics, is proposed. A subgrid model for particle decontamination, based on simulation of particle flow within individual bubbles of different sizes, is introduced first. Experimental data from the literature were then used to first validate the used open-source numerical solver’s gas–liquid flow part with the implemented drag model, and then to assess the results of pool scrubbing simulations using the implemented decontamination model.
