The aim of this work is to assess the possibilities of numerical simulation of the industrial slurry sedimentation process using ANSYS CFX software. Our work focused on the analysis of the simulation models available in the CFX module of the ANSYS to run the simulation of sedimentation based on the results of laboratory tests.
