Abstract:V diplomski nalogi smo obravnavali vpliv divergentnega kota na pojav kavitacije v Venturijevem kanalu. Z uporabo numeričnih metod v programskem okolju ANSYS Fluent smo izvedli simulacijo nestacionarnega večfaznega toka z vodo in vodno paro. Uporabili smo Zwart-Gerber-Belamri kavitacijski model in primerjali rezultate za dva različna divergentna kota 4° in 12°. Analiza je pokazala, da večji divergentni kot povzroča intenzivnejše nastajanje kavitacijskih oblakov in njihovo pogostejše odcepljanje.
Keywords:kavitacija, Venturijev kanal, divergentni kot, numerična simulacija, računalniška dinamika tekočin, večfazni tok, ANSYS Fluent, kavitacijski oblak, Zwart-Gerber-Belamri.

Title:Numerical analysis of the influence of diverging angle on cavitation in a venturi channel
Abstract:In this thesis, we investigated the influence of divergent angle on cavitation phenomena in a Venturi channel. Using numerical methods in the ANSYS Fluent, we performed a simulation of unsteady multiphase flow with water and water vapor. The Zwart-Gerber-Belamri model was applied, and the results were compared for two different divergent angles, 4° and 12°. The analysis showed that a larger divergent angle causes more intense cavitation cloud formation and more frequent detachment.
Keywords:c avitation, Venturi channel, divergent angle, numerical simulation, Computational Fluid Dynamics, multiphase flow, ANSYS Fluent, Cavitation cloud, Zwart-Gerber-Belamri.
