Lattice Boltzmann modeling-based design of a membrane-free liquid-liquid microseparatorStrniša, Filip (Avtor) Žnidaršič Plazl, Polona (Avtor) Plazl, Igor (Avtor) modeling-based designliquid-liquid separationmicrofluidicslattice Boltzmann methodThe benefits of continuous processing and the challenges related to the integration with efficient downstream units for end-to-end manufacturing have spurred the development of efficient miniaturized continuously-operated separators. Membrane-free microseparators with specifically positioned internal structures subjecting fluids to a capillary pressure gradient have been previously shown to enable efficient gas-liquid separation. Here we present initial studies on the model-based design of a liquid-liquid microseparator with pillars of various diameters between two plates. For the optimization of in silico separator performance, mesoscopic lattice-Boltzmann modeling was used. Simulation results at various conditions revealed the possibility to improve the separation of two liquids by changing the geometrical characteristics of the microseparator.20202021-05-17 10:16:32Članek v reviji127089UDK: 66.02ISSN pri članku: 0352-9568DOI: 10.15255/CABEQ.2020.1781COBISS_ID: 24458755sl
