Experimental Study of the Interaction Between a Premixed Confined Laminar Flame and Coherent Structures

  • D. Escudié

The present work deals with the experimental study of a premixed laminar V-shaped flame, expanding in a confined combustion chamber, and interacting with coherent structures.

A tomographic technique is used to visualize the flame front and a detailed description of the instantaneous velocity (Laser Doppler Anemometry) and mean temperature field (coated thermocouple) are used.

The results are interpreted in the light of preliminary flow characterization without combustion, regarding the vortex scales compared with the flame thickness and the position of the vortex generating cylinder.
