Characterizing the interaction of a vortex with a laminar opposed-jet flame

OSTI ID:20002664
The dynamic interaction of a laminar flame and a vortex is examined. The hydroxyl (OH) layer produced by the flame is imaged using planar laser-induced fluorescence (PLIF), and vortex-characterization data are acquired using digital, two-color particle-image velocimetry (PIV). The PIV and PLIF measurements of OH are performed simultaneously. The hydrogen-air flame is supported in a nonpremixed opposed-jet burner. The apparatus is found to produce highly repeatable events, making it ideal for studying the interaction of a flame and an isolated vortex. A distinct annular extinction of the OH layer is observed, in good agreement with previous computational modeling predictions for the apparatus.
