Abstract
This paper deals with the possibility of controlling various aspect of a non-premixed turbulent flame using an externally-imposed pressure gradient. From Turbulence measurement of the flame formed in a curved channel, it was shown that the mean pressure gradient caused the onset of counter-gradient heat transfer on the high-pressure side of the flame and promoted gradient diffusion on the low-pressure side. The flame behavior was strongly affected by these two contrasting phenomena. The present results indicate that we may find a novel approach to controlling turbulent combustion effectively using pressure gradients.
