N2 - Detailed understanding of the basic physical and chemical processes of self-ignition phenomena for technical fuel sprays is needed for different technical combustion applications. The multi-stage self-ignition behavior of single n-heptane droplets in air was studied at 580-1000 K and 0.3-1 MPa. The chemical reaction mechanism featured a 62-step kinetic model with special consideration of the low-temperature reaction branch. Cool flame and hot flame appearance were determined from non-intrusive interferometric measurement in a well tested experimental setup. A quantitative good agreement for first and total ignition delays, as well as for cool flame temperature were achieved. Using the detailed numerical model, the multi-stage ignition behavior was examined and the ignition criteria used in interferometric measurement were confirmed. Original is an abstract.
