Abstract
Computational analysis is performed with the objective to virtually represent objects and equipment’s real physical behavior. With simulation is possible to make geometrical and numerical modifications reaching the most efficient operational parameters of the equipment before its fabrication. A CFD-DEM coupled in one-way analysis join two distinct methods of calculation in a single solver, evaluating the iterations between fluid and particles. This article uses the CFD-DEM coupled analysis studying a filtration equipment that transport slurry (fluid + particles) to different exits. A rotational valve restraining the main exit, creates a raising pressure location forcing the slurry to go through a porosity region, with the objective to reduce the number of particles in the exiting water. It was possible to notice the behavior expected, as the influence of fluid in particles motion and the possibility to visualize the slurry flow to the exits, showing the regions where the slurry flow has preference to go through. Good visual results are demonstrated, indicating where the porosity media needs to be cleaned with more frequency avoiding clog.
