Abstract

Wall-stabilized cool flames were studied by both numerical and experimental methods. One- and two-dimensional numerical simulations in the axisymmetric condition were performed to estimate the characteristics of the cool flame, such as flammability and temperature/species distributions. A nozzle burner and heating plate were designed and fabricated for the experimental investigation of the cool flame. In the experiment, a wall-stabilized cool flame was observed for the first time through formaldehyde Planar Laser-Induced Fluorescence (HCHO-PLIF) measurements. The spontaneous initiation of lean cool flames at high wall temperatures, which was expected from S-curve calculations of the cool flame branch, was also successfully confirmed.
