Sažetak
Internal combustion engines are under constant development in terms of emission reduction and overall efficiency increase. In a modern engine engineering, the development is performed through the experimental research and by means of different computational approaches. Therefore, to contribute to development, a new computational method combining the Euler Eulerian multi-continuum approach and detailed chemistry kinetic was used to analyse the transient processes occurring within the engine combustion chamber. The method was compared to the widely-used Euler-Lagrangian spray approach, as well. The Euler Eulerian approach was previously verified and validated against spray and combustion processes modelling the constant volume chamber, and the approach was successfully employed for modelling of a direct injection diesel engine case. In this research, the computational model considers realistic liquid fuel injection process, liquid core disintegration, droplet atomization, and evaporation processes, as well as vapour combustion, emission formation and swirling motion. All of the mentioned processes are coupled with the complex moving mesh strategy. The purpose of the present research is to evaluate the capability of the newly developed method for calculating spray, combustion and emission processes for different engine operating points. The calculated results, which include the mean pressure traces, mean temperature, released heat, and emission concentrations are in a good agreement with the available experimental data. The computational simulations were performed with the commercial computational fluid dynamics code AVL FIRE™.
