Sažetak
In this paper, the numerical simulation of diesel engine combustion process with the commercial computational fluid dynamics software AVL FIRE® is presented. It is known than the spray process has an influence on the system efficiency that can be further increased by augmenting existing mathematical models. The combined effect of several parameters such as swirl, break-up model, and injection rate determine the spray characteristics, spray cloud shape, and the combustion process. In the observed experimental engine, the liquid fuel is injected through the pilot and main injections. The pilot injection is used to produce a small amount of vapour that ignites and increases the mean in-cylinder temperature before the main injection occurs. At later crank angle positions, around the top dead centre, the fuel is injected through the main injection process. In this research, the Euler Lagrangian spray approach was used for spray modelling. The special focus of this research is given to the comparison between combustion model ECFM 3Z+ and chemical mechanism used for modelling the combustion process. Finally, a comparison between the calculated and the experimental results is presented. The results from numerical simulations, such as the mean pressure and the rate of heat release are found to be in a good agreement with the experimental data.
