N2 - Two identical burners with variable burner separations are used to investigate the dynamics of interacting flames. The presence of adjacent flames in large scale combustion devices influences the structure and dynamics of the flames, and understanding the sensitivity of flames to these interactions is vital for local and global flame characterization. The behavior of the flame in the interaction zone is dependent on a number of operating parameters, including burner separations, inlet bulk flow velocities, and flame stabilization or flame shape. High-repetion-rate CH* chemiluminescence and OH-planar laser-induced flourescence measurements are performed to obtain the flame structure and flame-front locations. These measurement techniques allow for the determination of how varying fluid-dynamic and geometric parameters change the behavior of these flames in the flame interaction zones. We also quantify global metrics like flame surface density, global consumption speed, and flame curvature PDFs to understand the impact of flame interaction.
