2420 Numerical analysis of soot formation in premixed diesel combustion
Details
This work investigates the soot formation process in premixed diesel combustion using comprehensive soot model implemented into the KIVA-3V multidimensional CFD code. The numerical model is based on the KIVA code which is modified to use CHEMKIN as the chemistry solver. The soot model includes the particle inception, coagulation, surface growth and oxidation processes. It has been investigated that the effects of intake oxygen concentration and injection pressure on soot formation process in the premixed compression ignition (PCI) combustion with injection timing close to top dead center. The simulation results showed good levels of agreement with the measured in-cylinder heat release rate and soot emission. Also, the temporal profiles of in-cylinder soot mass were revealed.
