    CFD prediction of flow and homogenization in a stirred vessel

  • Original language description

    In this paper, the flow fields and transport of a tracer were simulated using commercial CFD package software. The results - velocity profiles, power and pumping numbers, concentration curves and mixing times, were compared with experiments in two vessels agitated by one or two impellers on the centric shaft. Two different impellers were used - 6-bladed 45° pitched blade turbine (PBT) and standard Rushton turbine (RT). The influence on the grid type was investigated. The standard k-epsĺ turbulence modeland Multiple Reference Frames method were used for the simulations.

    CFD simulace dob homogenizace v míchaných nádobách

  • Czech description

    V této práci bylo simulováno tokové pole a transport indikační látky pomocí komerčního CFD softwaru. Výsledky - rychlostní profily, průtoková a příkonová kriteria a doby homogenizace byly porovnány s experimenty ve dvou nádobách míchaných jedním a dvěmamíchadly na středové hřídeli. Byla použita dvě různá míchadla - míchadlo se šesti šikmými (45°) lopatkami (PBT) a standardní Rushtonova turbína (RT). Byl studován vliv typu sítě. Při simulacích byl použitý standardní k- model turbulence metoda mnohonásobné referenční soustavy.
