Original abstract
Multiphase gas-liquid-solid swirling flow within hydrocyclone is simulated. Geometry and boundary conditions are based on Hsiehs 75 mm hydrocyclone. Extensive simulations point that standard mixture model with careful selection of interphase drag law is suitable for correct prediction of particle classification in case of dilute suspensions. However this approach fails for higher mass loading. It is also confirmed that Reynolds stress model is the best choice for multiphase modeling of the swirling flow on relatively coarse grids.

Bylo simulováno vícefázové proudění směsi: voda-vzduch-pevné částice. Geometrie a okrajové podmínky odpovídají 75 mm hydrocyklonu dle Hsieh. Simulace ukázaly, že mixture model se správným modelem odporu mezi fázemi je schopen korektně simulovat distribuci pevných částic v řídkých suspenzích. Pro vyšší koncentraci částic tento model ovšem selhává. Potvrdilo se též, že model Reynoldsových napětí je nejlepším přístupem k simulování silně vírového proudění na relativně hrubých výpočetních sítích.
