Auto ignition tabulation of N-Heptane in ECFM-3Z Combustion Model

Recent efforts of implementing autoignition tabulated data to AVL's code "FIRE" including cool flame ignition will be presented in this paper, focused on n-heptane as fuel. Current use of n- heptane in combustion simulations did not include the phenomenon of cool flame ignition, and taking it into account could improve simulations of combustion in CI engines, also with wider application spectrum. The methods and ideas behind implementing the cool flame data into the ECFM-3Z model will be presented, as well as a comparison between the temperature fields calculated with ECFM-3Z model on a simple 100 cell mesh and a standalone application using Chemkin package.
