Vortex-Induced Flame Extinction In Two-Phase Counterflow Diffusion Flames With Ch Planar Laser-Induced Fluorescence And Particle-Image Velocimetry, Alix Lemaire, Terrence R. Meyer, Katharina Zahringer, Juan C. Rolon, James R. Gord
Terrence R Meyer
Here the interaction between a laminar two-phase, non-pre-mixed counterflow flame and a vortex is examined. Special emphasis is given to the influence of different flame and vortex parameters on the extinction behavior of the flame. Simultaneaous planar laser-induced fluorescence of the CH radical layer produced by the flame and particle-image velocimetry measurements of the flowfield are used to characterize the flame–vortex interaction. These simultaneous diagnostics are used for the first time in this configuration. The extinction processes occurring during the flame–vortex interaction can be analyzed by this method, especially the influence of strain at the flame surface. The influence of …
