20.500.12556/DKUM-86662 Reconstruction of a fluid bed device for separating granular material from the grinding process of rapid antigen tests The article includes the study and reconstruction of a fluid bed device with the purpose of separating the granular material from the grinding process of rapid antigen tests. The following techniques were performed, with the purpose of characterisation of the ground particles: sieve analysis, X-ray fluorescence spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy. The paper includes experimental testing of a simplified separation process with zeolite spheres and paper strips, supported by a numerical model. The flow conditions’ impact on the behaviour and interactions of particles of the considered problem were simulated using coupled computational fluid dynamics (CFD) and the discrete element method (DEM) approach. The separation process of zeolite spheres and paper strips was found to be efficient. The simulation results showed the appropriate behaviour of the particles during the process. We explained the results’ deviations, and we also presented the shortcomings and possible improvements. Further research is required to define the adequacy of the process, while using actual ground material of rapid antigen tests. rapid antigen tests nanomaterials fluidised bed computational fluid dynamics discrete element method characterisation hitri antigenski testi nanomateriali računalniška dinamika tekočin metoda diskretnih elementov karakterizacija true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/processes Znanstveno delo 2024-01-05 10:38:38 2024-01-05 12:38:10 2024-11-11 14:42:43 0000-00-00 00:00:00 2023 0 0 Str. 1-13 št. 11, št. članka 3207 Letn. 11 Nov. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-10-24 2023-11-08 2023-11-10 620.1:519.6 171870467 10.3390/pr11113207 2227-9717 Jordan-2023-Reconstruction_of_a_Fluid_Bed_Devi.pdf Jordan-2023-Reconstruction_of_a_Fluid_Bed_Devi.pdf 1 7B79F24358E49A93890AAC0CF4D53635 716f25a40a25382cb94ea54c3f4e419cd8655394fed426da1225cb2adfa70055 876e35a6-abb0-11ee-afd5-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=175106 https://doi.org/10.3390/pr11113207 0 bcd66268-abbc-11ee-afd5-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=175114 Fakulteta za strojništvo 0 0 0
