A Study of Ignition Delay of Diesel Combustion by Using Computational Fluid Dynamics Simulation

Abstract

A numerical study was carried out to predict ignition delay times by using KIVA-3 combined with the ignition model, which is based on Livengood-Wu theory. N-heptane was selected on the basis of similarity of cetane number to diesel oil. The experimental data for n-heptane^<(1)> was referred to certify the adjustment of this model. The computational results show relatively good agreement between computational predictions and experiments.
