RÉSUMÉ
The present paper reports results of high-repetition PIV measurements of flow in a rich propane-air lifted flame. The flow characteristics were compared to these for non-reacting flow, and it was observed that the presence of combustion significantly affected development of the flow disturbances in the shear layer upstream. Intensity of the velocity fluctuations and their characteristic frequency were significantly greater in comparison to the non-reacting case. Additionally, a periodic forcing of bulk velocity at fundamental frequency was applied for the reacting flow in order to emphasize role of large-scale vortices in stabilization of the flame.
