The paper sets an example of modeling the expansion and bed pressure drop of the cohesive and problematic material - titanium dioxide modified by Aerosil R972 in program Ansys / CFX - Fluent using two multiphase models, Euler Fluid-Granular Model and Dense Discrete Phase Model at certain predefined conditions in a square section fluidized bed cell. The variables bed pressure drop, particle concentration in volume and velocity field of solid particles were defined for the simulations in metallurgical processes.The research follows on from the previous study of simulating the arrangement of spherical particles with a diameter of 2-10 mm and compares them with the experiment, where it was discovered, that the square section fluidized cell achieves the best results with spherical particle arrangements of diameter 8 mm.
