“…The results of studying on cyclone flow field reveal that Reynolds stress transport model yields results in good agreement with experimental data [5][6][7]. Due to the similarity between the flow fields in cyclones and a vortex engine this method is used to simulate the flow field inside the chamber.…”

“…A numerikus áramlástan, CFD (Computational Fluid Dynamics) segítségével [7] az utóbbi években több publikáció is megjelent az előzőkben vázolt, igen bonyolult áramkép leírására [8,9]. A 3D-s örvénymozgás numerikus kezelésekor a turbulencia modellek validálását azonban minden esetben el kell végezni, ami viszont csak gondosan kivitelezett, korszerű méréstechnikával, például a kétsugaras LDV (Laser Doppler Velocimetrie) vagy a Műszaki Kémiai Kutató Intézetben is használt PDPA (Phase Doppler Particle Analyzer) használa-tával végzett kísérletek adataival lehetséges.…”

“…Svéd kutatók a közelmúltban már a hengeres hidrociklon numerikus modellezéséről számoltak be [9]. Az általuk vizsgált hidrociklon -a 10. ábrával ellentétben -megfordítva működött, azaz a szétválasztandó közeg alul lépett be tangenciálisan kialakított furatokon keresztül a hengeres testbe, míg az elvezetések, mind a tangenciális kifolyás, mind az örvénykereső cső, felül helyezkedtek el.…”

“…To obtain the pressure field inside the hydrocyclone, the semi-implicit pressure linked equations (SIMPLE) algorithm was used for combination of continuity and momentum equations for two phases [16]. The quadratic upstream interpolation for convective kinetics (QUICK) schemes was applied for the interpolation of the field variable from cell centers to faces of control volumes as it was reported to be useful for swirling flows [17,18]. Simulations were carried out for about 70000 incremental steps and time steps were set to 0.001.…”
