要約

The aim of this experimental study is to point out the turbulence effect on the stabilisation mechanisms of a non-premixed flame. With this objective, a non-premixed methane-air flame stabilised on a tulip bluff-body is investigated. By means of direct visualisations and laser Doppler anemometry, an accurate description of the aerodynamic flow is provided. The influence of turbulence on the non-premixed stabilisation diagram is first described. Results point out an earlier transition of the five different regimes. Then the specific laminar ring flame region, where stabilisation is linked to the existence of a triple point, is particularly detailed. The main effect of turbulence is to modify the ring flame position and shape. A regular wave appears which analysis needs further development.
