Abstract:Prispevek obravnava numerično modeliranje mešanja newtonske tekočine v mešalni posodi, v kateri je nameščeno turbinsko Rushtonovo mešalo. Obravnavan je ustaljeni turbulentni tokovni rezim, opisan s časovno povprečnim Navier-Stokesovim sistemom enačb. Numerično reševanje temelji na uporabi dvoenačbnega modela turbulence in metode končnih prostornin. Posebna pozornostje namenjena modeliranju vrtenja mešala ter izračunu mehanske moči za mešanje, kakor tudi nekaterim poenostavitvam, ki omogočajo hitrejši izračun zahtevnih diskretnih modelov.

Title:Numerical modeling of mixing in a vessel with a Rushton impeller
Abstract:This paper presents numerical modeling of mixing a Newtonian fluid in a stirring vessel with a Rushton impeller. The stationary turbulent flow is governed by the time-averaged Navier-Stokes equations. For the numerical approach, a two-equation turbulence model with the finite-volume method was used. The focus is on impeller rotation, a determination of the stirrer power and a simplification that can lead to faster solving of complicated discreet models.
