Abstract

A new high temperature, high Reynolds number, flow reactor coupled counterflow edge flame burner has been developed providing a well-defined flow geometry and fuel/oxidizer reactivity to explore the flame regimes experienced in high speed engines. The turbulent flow characteristics of the new burner have been quantified using hot wire anemometry and methane/air flames at bulk Reynolds numbers exceeding 30,000 have been achieved. Planar laser induced fluorescence measurements for OH have been performed on the highly turbulent methane/air flames providing an accurate description of the flame surface leading to determination of turbulent burning velocities and flame surface densities. The measured CH4/air turbulent flame speeds agree well with previously reported turbulent flame speed correlations derived from different burner/flame geometries. These preliminary data provide a foundation from which to pursue an understanding of the complex turbulent/chemistry behavior that occur in many practical high speed engines.
