Abstract
The 3-D CFD code could be a very useful tool to predict diesel combustion and emissions formation and reduction. The code is required to reproduce phenomenological processes such as atomization, evaporation and mixing with air. In addition, detailed chemistry should be taken into account for modeling combustion. For this purpose, in the present study, the hybrid Kelvin-Hehnholtz/Rayleigh-Taylor droplet breakup sub-model is introduced to describe spray atomization characteristics under high pressure and temperature conditions. The sub-model based on the Partially Stirred Reactor (PaSR) is also used to represent the interaction between turbulent mixing and detailed gas phase chemical kinetics. These sub-models are then improved and validated by comparing with experimental results.
