Abstract
U ovom radu analizirane su mogućnosti kalibracije modela izgaranja uz korištenje što manje radnih točaka da bi se dobilo dobro poklapanje rezultata simulacije s eksperimentalnim rezultatima u cijelom radnom području motora. Motor korišten u simulaciji je četverotaktni Otto motor proizvođača Fiat za koji su u laboratoriju izmjereni podaci u 162 radne točke. Simulacije rada motora provedene su u programskom paketu AVL BoostTM. Kalibracija je provođena za model praćenja plamena FTM i kvazidimenzijski model rasta jezgre plamena. Nakon postavljanja ulaznih parametara modela na početne vrijednosti prvo je provedena analiza osjetljivosti pojedinih parametara, a onda je na temelju tih rezultata provedena kalibracija modela na 15 odabranih radnih točaka. Tako kalibriranim modelima provedena je analiza za cijelo radno područje motora te su rezultati uspoređeni s eksperimentalnima. Zatim je određen minimalan broj radnih točaka za kalibraciju modela izgaranja i kvazidimenzijskog modela rasta jezgre plamena.
Abstract (english)
In this thesis, the possibility of calibration of combustion model is analysed with the use of fewer operating points in order to obtain a good match between results of simulation with experimental results in whole working space of engine. The engine used in simulation is a four-stroke Otto engine of Fiat manufacturer for wich data in laboratory were measured in 162 operating points. Simulation of engine operation was carried out in program AVL BoostTM. Calibration was performed for flame tracking model FTM and quasi-dimensional model of growth kernel flame QDIM. After setting the input parameters of model to initial values, sensitivity analysis of individual parameters was first performed and then based on these results calibration model was performed on 15 selected operating points. So calibrated models performed an analysis for entire engine operating range and results were compared with experimental. Minimum number of operating points were specified for calibration of combustion model and quasi-dimensional model of growth kernel flame.
