Abstract
The differences between spray models are investigated by comparing calculation results with experimental data. The calculations are performed using the KIVA-II code. The spray models TAB, which is the original model of KIVA-II, and the model developed by Reitz are calculated and compared. A semi-empirical spray model based on the TAB model is also formulated and compared with the other models. The penetration and droplet size distribution are compared with data from constant pressure bomb tests. The calculated ignition delay is compared with actual engine operating data- Each spray model has different characteristics influencing the atomization process. These differences result in discrepancies during the penetration, evaporation, and ignition.
