Much fundamental research on flame extinction caused by chemically active agents has been performed in premixed and counterflow flames. However, most fires are more closely described by co-flow diffusion flames. This research seeks to understand the mechanisms of flame stabilization in the presence of chemical inhibitors added to the fuel or oxidizer stream.

The research combines numerical and experimental approaches. The numerical work will involve a time-dependent DNS model with full and reduced chemistry. Diagnostic equipment includes particle image velocimetry, emission spectroscopy, laser scattering and extinction, and Phase-Doppler Particle Analysis. Opportunities also exist for measurements using laser spectroscopy and mass spectrometry. The goal is to fully characterize the flame so that the influence of the chemical inhibitors on the stabilization region can be determined.
