20.500.12556/DKUM-94678 Numerična analiza toka v laminarizatorju plinskega gorilnika diplomsko delo Numerical analysis of flow in the laminarizer of a gas burner Plinski gorilniki predstavljajo ključne elemente ogrevalnih sistemov, kjer sta učinkovitost zgorevanja in emisije škodljivih snovi odvisni od pretočnih karakteristik mešanice plinskega goriva. V tej študiji smo raziskali pretok skozi laminarizatorje plinskega gorilnika Weishaupt z namenom ugotoviti, ali se turbulentni tok znotraj njih ponovno laminarizira. Podrobno smo analizirali hitrostne profile skozi izbrane luknjice v pomanjšani geometriji ob upoštevanju vpliva lokacije, izbire medija (zrak ali vodik) ter primerjave med laminarnim in GEKO tokovnim modelom. Rezultati simulacij kažejo, da lokacija laminarizatorja in izbira medija pomembno vplivata na porazdelitev hitrosti zaradi kompleksne tridimenzionalne narave toka, medtem ko je vpliv izbire tokovnega modela zanemarljiv. Pridobljeni izsledki ponujajo trdno podlago za nadaljnjo optimizacijo geometrije in delovanja gorilnika. Gas burners represent key components of heating systems, where combustion efficiency and harmful emissions depend on the flow characteristics of the fuel–air mixture. In this study, we investigated the flow through the laminarizers of a Weishaupt gas burner with the aim of determining whether turbulent flow within them can become laminar again. We performed a detailed analysis of velocity profiles through selected holes in a scaled-down geometry, considering the influence of location, choice of medium (air or hydrogen), and a comparison between the laminar and GEKO viscous models. The simulation results indicate that the location of the laminarizer and the choice of medium significantly affect the velocity distribution due to the complex three-dimensional nature of the flow, while the influence of the viscous model selection is negligible. The findings provide a solid basis for further optimization of the burner’s geometry and operation. plinski gorilnik laminarizator cfd simulacija turbulentni in laminarni tok vodik gas burner laminarizer CFD simulation turbulent and laminar flow hydrogen true true false [M.
