20.500.12556/DKUM-69184 Numerična analiza procesa oblaganja tablet z uporabo sklopljene CFD-DEM simulacije Numerical analysis of tablet coating process using coupled CFD-DEM simulation Magistrsko delo zajema računalniški pristop k modeliranju procesa oblaganja tablet. Interakcije med delci so simulirane s pomočjo metode diskretnih elementov (DEM). Tok zraka znotraj obravnavanega območja je simuliran s pomočjo metode računalniške dinamike tekočin (CFD). Cilj dela je bil izvesti CFD-DEM sklopljeno simulacijo, analizirati vpliv vhodnih parametrov na rezultate simulacije in analizirati vpliv procesnih parametrov na učinkovitost procesa oblaganja tablet . Skupno je izdelano 9 DEM in 8 sklopljenih CFD-DEM simulacij na podlagi katerih so bili analizirani rezultati. Rezultati simulacij so pokazali, da zrak in njegove lastnosti imajo pomemben vpliv na učinkovitost procesa, pri čemer povečevanje hitrosti zraka na vstopu povzroča spremembo oblike razprševalne tekočine in hitreje segrevanje tablet. Iz tega je ugotovljeno, da je vloga zraka ključnega pomena v procesu oblaganja tablet, in je sklopljeni pristop simuliranja pomemben za natančen opis takšnih procesov. Master's thesis describes a computational approach in tablet coating process modeling. Particle interactions are simulated using discrete element method (DEM). Fluid flow inside the observed zone is simulated using computational fluid dynamics methods (CFD). The goal of this thesis is to realize a coupled CFD-DEM simulation, analyze the effect of input parameters on simulation results and to analyze the influence of process parameters on the efficiency of tablet coating process. In order to analyze the results, a total of 9 DEM and 8 coupled CFD-DEM simulations were performed. Results of simulations showed that air and its properties can have a significant impact on the efficiency of the process, where higher inlet air velocities caused a change in spray shape and increased the tablet heating rate. This led to the conclusion that the role of air is crucial in a tablet coating process, and that coupled simulation approach is necessary for an accurate description of such processes. računalniška dinamika tekočin metoda diskretnih elementov sklopljena CFD-DEM simulacija proces oblaganja tablet computational fluid dinamics discrete element method coupled CFD-DEM simulation tablet coating process true true false [P.
