Autoignition and Combustion of Diesel and JP-8

Abstract

Experimental and numerical studies are carried out to construct reliable surrogates that can reproduce aspects of combustion of JP-8 and Jet-A. The combustion characteristics considered are extinction and autoignition in laminar non-premixed flows. Three surrogates are constructed. The measured values of the critical conditions of extinction and autoignition for the surrogates are compared with those for the jet fuels. Numerical calculations are carried out using a semi-detailed chemical-kinetic mechanism. The calculated values of the critical conditions of extinction and autoignition for the surrogates are found to agree well with experimental data. The research is performed in collaboration with Professor Eliseo Ranzi at Politecnico di Milano, Italy.
