20.500.12556/RUL-127171 Inertial focusing of neutrally buoyant particles in heterogenous suspensions The modelling-based design of microfluidic devices leads to highly efficient process intensification, which provides insights into different temporal and spatial scales at which processes in various fields of application could be performed. This requires not only an understanding of the underlying mechanisms of different processes at the micro scale, but also the development of relevant computational tools. The macroscopic models are often unable to produce conclusive evidence for a given mechanism in systems with the complexity characterizing almost all chemical and biochemical processes. By contrast, mesoscale methods possess the unique ability to model relatively large physical systems, and, at the same time, effectively capture the essential features of the micro- and nanoscale structure, architecture, and relevant interactions. We demonstrate the feasibility and usefulness of this novel tool by considering a movement of neutrally buoyant particles in straight microchannels. The two-dimensional lattice Boltzmann method with immersed boundary conditions was used to study the influence of Reynolds number and particle diameter ratio on formation of particle trains. It was shown that an increase in particle diameter ratio leads to a less stable final particle configuration. An increase in Reynolds number was not found to significantly influence the train stability in the tested range. inertial lift lattice-Boltzmann method immersed-boundaries mikrofluidi mrežna Boltzmannova metoda true false true Angleški jezik Slovenski jezik Članek v reviji 2021-05-21 09:52:48 2021-05-21 10:13:47 2022-09-06 03:50:01 0000-00-00 00:00:00 2021 0 0 7 str. art. 115410 Vol. 328 15 Apr. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 544.27:66.02 0167-7322 10.1016/j.molliq.2021.115410 48091395 RAZ_Hubman_Anze_2021.pdf RAZ_Hubman_Anze_2021.pdf 1 1EAB5A40F1F5BF27A4890B71974DA949 ebff3fc7a966bdeb7db8fab4e6a9e3d8e3f6b70673e9d770eee2023a3ce048f8 e9f37fa7-c2d8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143599 https://www.sciencedirect.com/science/article/abs/pii/S0167732221001367 1 7d0af142-ba09-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143422 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
