20.500.12556/RUL-136997 Characterization of a convection-based support microstructure through a flow resistance parameter Modern convection-based supports differ substantially in pore size, porosity, and microstructure topology. Due to such variability, it is challenging to evaluate the contribution of a particular microstructure topology on flow resistance. We demonstrated that the flow resistance parameter (Φ) introduced decades ago can be used as a criterion to evaluate the effect of microstructure topology on a pressure drop when the pore size is used as a characteristic support dimension. Furthermore, the Φ value of simple cubic packing was calculated over the entire range of open porosity and compared to the Φ values determined for pressure drop models derived for particular convection-based supports and experimental values of various convection-based supports from the literature. It was shown that different convection-based supports become clustered into distinct groups when plotted according to their Φ and open porosity values, allowing their discrimination. convection-based support flow resistance parameter microstructure pressure drop na konvekciji temelječi nosilci parameter upora toku mikrostruktura padec tlaka true false true Angleški jezik Slovenski jezik Članek v reviji 2022-05-27 15:44:44 2022-05-27 15:44:45 2022-09-15 04:14:34 0000-00-00 00:00:00 2022 0 0 Str. 1984-1996 iss. 12 Vol. 45 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 66.021.2 1615-9306 10.1002/jssc.202100955 99002883 brez_reklamne_strani_J_of_Separation_Science_-_2022_-_Podgornik_-_Characterization_of_a_convection‐based_support_microstructure_through_a_flow.pdf brez_reklamne_strani_J_of_Separation_Science_-_2022_-_Podgornik_-_Characterization_of_a_convection‐based_support_microstructure_through_a_flow.pdf 1 CA6418BC16C2D9F7C8905EA4AF761350 a2b9490bc9b4fc0a81f6e2e1d2c816bde062822437efd1948fdbef4c075dd50d c917411d-3348-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=160922 https://analyticalsciencejournals.onlinelibrary.wiley.com/doi/10.1002/jssc.202100955 1 077cd1b9-ddc3-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156839 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
