Model razvlaknjenja taline na dvokolesni centrifugi
Marko Blagojevič, Benjamin Bizjan
Diplomsko delo
Oznake: diplomske naloge;mineralna volna;razvlaknjenje taline;primarna plast;centrifuga;tok odpiha;vizualizacija toka;
Razvlaknjenje taline mineralne volne je kompleksen proces, katerega poznavanje je ključnega pomena pri proizvodnji izolacijskih materialov. Postavili smo preizkuševališče, ki omogoča proučevanje procesa razvlaknjenja. Pomembni vhodni parametri, ki vplivajo na proces, so vrtilna frekvenca koles centr ...

Modeliranje in optimizacija prostega natoka taline na centrifugo za proizvodnjo kamene volne
Marko Blagojevič, Benjamin Bizjan
Magistrsko delo
Oznake: magistrske naloge;kamena volna;numerični model;prosti natok kapljevine;iztočni kanal;vizualizacija toka;kolesna centrifuga;
V delu je bila opravljena vizualizacija vpliva hitrosti kolesne površine in hitrosti curka na obliko in škropljenje kapljevine v okolici natočnega mesta z uporabo hitre kamere. Izvedena je bila vizualizacija prostega toka modelne kapljevine iz kanala s prerezom v obliki črke V pod kotom 90°. Izdelan ...

Analogue experimental study of fiber formation on two-wheel spinner
Benjamin Bizjan, Brane Širok, Marko Blagojevič
Izvirni znanstveni članek
Oznake: spinners;fiber formation;mineral wool;multiphase flow;primary layer;high-speed imaging;
In this paper, the process of mineral fiber formation was investigated experimentally on a two-wheel spinner by means of high-speed imaging. Analogue isomalt melt was fiberized at different rotational speeds of spinner wheels, melt flow rates and impingement positions so that the fiberization proces ...

Free surface lubrication of rotating cylinders by impacting Newtonian liquid jet
Benjamin Bizjan, Brane Širok, Marko Blagojevič
Izvirni znanstveni članek
Oznake: prosta površina;omočenje;hidravlična nestabilnost;pljuskanje;free surface lubrication;hydraulic jump;lamella instability;liquid jet impingement;rotating surface;splashing;
Free surface lubrication of rotating cylinders by Newtonian liquid jets was investigated at different impingement positions, jet- and circumferential velocities. The interaction between impinging round laminar jet and rotating surface was characterised by high-speed imaging. Compared to flat surface ...

Numerical modeling of laminar free overfall in triangular channels
Primož Drešar, Marko Hočevar, Marko Blagojevič, Benjamin Bizjan
Izvirni znanstveni članek
Oznake: free overfall;open channel flow;laminar flow;computational fluid dynamics;volume of fluid;end depth ratio;laminarni tok;računalniška dinamika tekočin;tok v odprtih kanalih;
Design of open channel transport and flow measurement systems for highly viscous liquids requires accurate modelling of laminar free overfall. In this study, a computational fluid dynamics model was developed to investigate subcritical laminar free overfall in smooth horizontal channels with 90° iso ...

ǂA ǂreview on rotary generators of hydrodynamic cavitation for wastewater treatment and enhancement of anaerobic digestion process
Marko Blagojevič, Gašper Rak, Benjamin Bizjan, Sabina Kolbl
Pregledni znanstveni članek
Oznake: hidrodinamska kavitacija;odpadna voda;aktivno blato;anaerobna presnova;biometan;rotacijski generator hidrodinamske kavitacije;wastewater treatment;waste activated sludge;anaerobic digestion;biomethane;rotary generator of hydrodynamic cavitation;
The issue of ever-increasing amounts of waste activated sludge (WAS) produced from biological wastewater treatment plants (WWTPs) is pointed out. WAS can be effectively reduced in the anaerobic digestion (AD) process, where methanogens break down organic matter and simultaneously produce biogas in t ...
