20.500.12556/DKUM-16847 PREHOD IZ MERITEV NA SIMULACIJSKI 3D IN 1D MODEL ZGOREVANJA ZA DIZELSKI DI MOTOR TRANSITION FROM MEASUREMENTS TO 3D AND 1D COMBUSTION SIMULATIONS FOR A DI DIESEL ENGINE Zgorevanje v dizelskih motorjih je mogoče simulirati s pomočjo programske opreme, ki je danes na trgu že zelo razširjena. Vedno bo ostajalo število neraziskanih področij, ki se odkrivajo ob vpeljavi teh simulacijskih orodij. V tej nalogi sem na podlagi meritev in 3D, Fire simulacij sestavil 1D, Boost simulacijski model DI-dizelskega motorja z MCC-modelom zgorevanja, ki sem ga nato nastavil/umeril in rezultate primerjal z meritvami. Ujemanje je pokazalo, da je izbrana metoda dobra in da so simulacijski prijemi sposobni napovedovati trende obnašanja motorjev pri različnih obratovalnih pogojih. V prihodnosti je mogoče naredi še veliko, da se 1D- in 3D-simulacije zgorevanja dodatno zbližajo. Combustion in diesel engines can be simulated with the assistance of modern software that is wide spread on the market nowadays. There will always be a wide uncertain field which can be uncovered with implementation of these tools. In the presented diploma work I have constructed a 1D Boost model of a DI diesel engine with usage and calibration of MCC combustion model, based on measurement results and an available 3D Fire model. Analysis of the results showed that calibration method was successful and simulation tools are capable to predict engine behavior at different operating points. In the future, additional work can bring 1D and 3D combustion simulations even closer together. zgorevanje dizelski motorji simulacijske metode 1D- in 3D-simulacije motorjev zgorevalni motorji Combustion Diesel engines Simulation tools 1D and 3D engine simulations Combustion engines true true false [J.
