    CFD simulations of the clear liquid layer formation in dense solid-liquid suspension

  • Original language description

    In this work, the CFD simulation abilities for stirred solid-liquid dense systems are explored, namely with particle average concentrations up to 15 vol.%. These suspension systems may give rise to the formation of a thick and well-defined clear liquid layer in the upper part of the vessel, whose extension progressively reduces while increasing impeller speed. Present Eulerian-Eulerian CFD simulation techniques were found to be able to correctly reproduce the phenomenon.oncentrations up to 15 vol.%.

    CFD simulace tvorby vrstvy čisté kapaliny v koncentrovaných suspenzíchI

  • Czech description

    V této práci jsou studovány možnosti CFD simulace míchaných systémů pevná fáze-kapalina, a to při průměrných koncentracích částic až do 15 objemových procent. V suspenzních systémech může v horní části nádoby vznikat zřetelná vrstva čiré kapaliny, jejížrozměr se zmenšuje se zvyšující se rychlostí míchadla. Dostupná Euler-Eulerova CFD simulační metoda správně popisuje tento jev.
