dc.description.abstractIn this study, the effect of spray cone angle on spray dynamics of DI diesel engine equipped with common-rail fuel injection system is investigated numerically using a multidimensional Computational Fluid Dynamics (CFD) simulation tool, AVL-FIRE code. The in-cylinder spray dynamics such as spray and vapor penetration, droplet diameter, and Turbulence Kinetic Energy (TKE) as well as droplet distribution are investigated for different spray cone angles changed from 120o to 160o . The simulation results indicate that the selected spray cone angle actually changed all spray dynamics. Spray and vapor penetration and droplet diameter are affected with increasing spray cone angle. In-cylinder air motion was later studied for a number of spray cone angles, which identified a slightly changed in-cylinder Turbulence Kinetic Energy (TKE) around the compression top dead center (TDC). Additionally, it was determined that spray cone angles have considerable affects the fuel spray dynamics. Both liquid and vapor penetration are directly linked to the spray cone angleen_US
