Structures and propagation speeds of autoignition-assisted premixed n-heptane/air cool and warm flames at elevated temperatures and pressures

The laminar flame speeds and structures of near-limit autoignition-assisted cool and warm n-heptane/air flames at different ignition Damkӧhler numbers which are the ratios between flow residence time and the ignition delay time, elevated temperatures and pressures are studied computationally and analytically over a broad range of equivalence ratios. The primary objective of this work is to understand the effects of the ignition Damkӧhler number,...
