Abstract
The present work is devoted to the experimental study of the axial forcing effect on propane-air and methane-air lifted turbulent flames. The forced flames without swirl and with strong swirl were studied by means of stereo PIV. The spatial distributions of the average velocity and components of turbulent kinetic energy were measured. Dynamics of the large-scale vortices was also investigated by means of high-repetition stereo PIV. For the strongly swirling propane-air flame with vortex breakdown, it was observed that the high-amplitude axial forcing can provide an increase of turbulent combustion rate and suppress vortex core precession near the nozzle exit due to interaction of ring vortices with the flame.
