Abstract:	Diplomsko delo obravnava sklopljeno CFD – DEM numerično simulacijo mešanja dvofazne zmesi znotraj mešalne naprave. Mešanje je bilo simulirano v mešalni posodi s štirimi pregradami in z uporabo Rushtonovega turbinskega mešala s 6 ravnimi lopaticami. Prvi del diplomske naloge opisuje teoretične osnove obravnave večfaznih tokov, s pomočjo enačb opisuje matematično ozadje izvedenih CFD in DEM simulacij, ter na kratko povzame pomen in delovanje kontaktnih modelov v DEM simulacijah. Drugi del diplomske naloge opisuje postopek priprave sklopljene simulacije, ter interpretira dobljene rezultate in jih primerja z eksperimenti, izvedenimi v laboratoriju Fakultete za strojništvo, Univerze v Mariboru. Primerjava je kvalitativna in temelji na opazovanju premikanja in obnašanja delcev v tekočini, pri različnih vrtilnih hitrostih mešala.

Title:	Numerical analysis of multiphase flow in cooking device using coupled simulation
Abstract:	The diploma thesis discusses the coupled CFD – DEM numerical simulation of mixing of a multiphase mixture inside of a mixing device. The mixing was simulated inside of a mixing vessel with four barriers, using a Rushton turbine with 6 straight blades. The first part of the diploma thesis presents the theoretical foundations of multiphase flows, describes the mathematical background of the simulations using the corresponding equations, and describes the meaning and working of contact models briefly. The second part of the diploma thesis presents the preparation of the coupled simulation and interprets the acquired data. The simulation data was also compared to the results acquired via real experiments conducted in the laboratory of the Faculty of Mechanical Engineering, University in Maribor. The comparison was qualitative and it focused on the movement and behavior of the simulated particles at different rotational velocities of the mixer.
Keywords:	mixing, mixing vessel, coupled CFD – DEM simulation, multiphase flow
