Simulation of Liquid Phase Penetration in Diesel Spray 2001-01-3229

In order to investigate on the complex phenomena that occur in the evolution of an evaporating fuel spray (like break up, fuel multicomponent evaporation, liquid gas interaction) a numerical analysis has been carried out. The numerical tool used is a modified version of the well known KIVA code in which a new break up model, developed and validated in previous work [1, 2], and a fuel multicomponent evaporation model have been included. The predictive capability of the evaporation model has been evaluated by comparison with single droplet experimental data [3]. Then the code has been used to evaluate the influence of fuel and injection system parameters (nozzle diameter and injection pressure) on spray penetration and morphology.
