Multiscale Modeling of Autoignition-Assisted Cool Flames at High Temperatures and Pressures

The laminar flame speeds and chemical kinetics for cool and warm n-heptane/air flames at different ignition Damkӧhler numbers under elevated temperatures and pressures are numerically modeled in a broad range of equivalence ratios with detailed chemistry. The primary focus of the current study is placed on the effects of ignition Damkӧhler number and pressure on near-limit cool flames propagation. The results show cool flame speeds increase...
