Abstract

Računalniška dinamika tekočin predstavlja učinkovito orodje pri iskanju izboljšav na področju motorjev z notranjim zgorevanjem. Razvoj komercialnega programa FIRE, ki temelji na metodi končnih prostornin, poteka v smeri razvijanja in dodajanja novih modelov, ki upoštevajo nove formule za natančnejši izračun. Te naprednejše modele bi bilo smiselno ponuditi uporabnikom kot privzete parametre za podobne industrijske simulacije. V okviru naloge je prikazana študija posameznih modelnih konstant različnih emisijskih modelov za oceno emisij saj na primeru AVL-ovega raziskovalnega Dizel motorja FM530, in sicer za 5 različnih ESC (European Stationary Cycle) obratovalnih režimov, za katere obstajajo meritve tlaka in emisij. Študija je pokazala, da se s spremembo posameznih parametrov in s starimi nastavitvami ni mogoče približati eksperimentalnim vrednostim.

Secondary title:	Numerical analysis of emission model influence factor in diesel engine
Secondary abstract:	Computational fluid dynamics represents an effective tool in the search for improvements in internal combustion engines. FIRE commercial development program based on finite volume, takes place in a context of evolving and adding new models to reflect the new formula for accurate calculation. These advanced models would be appropriate to offer users a similar default parameters for industrial simulation. The study shows the functions of each model constants of the various emission models to estimate emissions as the case AVL Diesel Engine Research FM530 by 5 different ESC (European Stationary Cycle) operating regimes for which there is pressure and emission measurements. The study showed that the change of the parameters and the old configuration can not be closer to experimental values.
