Abstract

Cilj tega dela je bil ugotoviti porazdelitev pretoka zraka na razdelilni plošči laboratorijske naprave za granuliranje v lebdečem sloju. Želeli smo ugotoviti ali sprememba pretoka zraka na napravi vpliva na delež pretoka skozi posamezno območje razdelilne plošče, kjer smo območja razdelili glede na premer odprtin v plošči. Za določitev porazdeljevanja pretoka praznega granulatorja smo izvedli 6 numeričnih simulacij toka zraka s programskim orodjem AVL Fire (računalniška dinamika tekočin) in 6 dvosmerno sklopljenih AVL Fire—XPS (računalniška dinamika tekočin – metoda diskretnih elementov) simulacij toka zraka z delci pri obratovanju polne naprave. Ugotovili smo, da pretok zraka skozi napravo vpliva na porazdelitev pretoka zraka na razdelilni plošči, posebno v primeru polne naprave.

Secondary title:	Determination of air flow rate distribution on distributor plate in fluidized bed granulator using coupled numerical simulation of fluid flow and particles
Secondary abstract:	The goal of this thesis was to determine distribution of air flow on distributor plate of a laboratory scale fluidized bed granulator. We wanted to determine whether the change in air flow rate influences the fraction of air flow passing through distinct sections of distributor plate, which we divided based on the diameter of the openings in the plate. To determine air flow distribution in an empty granulator we performed 6 numerical simulations of air flow using AVL Fire code (computational fluid dynamics) and 6 two way coupled AVL Fire—XPS (computational fluid dynamics—discrete element method) simulations of air flow with particles in the case of granulator filled with particles. We found that air flow rate influences the distribution o fair flow on distributor plate, particularly in the case of granulator filled with particles.
