20.500.12556/DKUM-68182 Cfd simulacija ejektorja za sofc kogeneracijski sistem Cfd simulation of an ejector for sofc chp system S pomočjo računalniške dinamike tekočin je bila opravljena preiskava geometrije plinskega ejektorja. Plinski ejektor se uporablja v kogeneracijskem sistemu trdo oksidnih gorivnih celic in omogoča recirkulacijo anodnih izpušnih plinov. CFD preiskava je bila opravljena s pomočjo programskega paketa AVL Fire. Cilj naloge je primerjava rezultatov simulacij z meritvami in preiskava vplivov sprememb geometrije ejektorja. Meritve v magistrski nalogi niso bile opravljene, temveč so bili rezultati pridobljeni. Geometrijske spremembe, ki smo jih preiskovali so položaj primarne šobe, premer mešalnega dela ejektorja in oblika primarne šobe An investigation of gas ejector geometry has been performed with computational fluid dynamics. Investigated ejector is used in combined heat and power solid oxide fuel cell system and allows anode exhaust gas recirculation. CFD investigation has been performed with software package AVL Fire. The aim of this thesis is to compare the measurements with simulation results and to investigate the influence of geometry changes on performance of gas ejector. Measurements are not part of this thesis, only the results have been acquired. Investigated geometry changes are primary nozzle position, mixing section diameter and primary nozzle design.
