Combustion Measurements in a Counter-Flow Burner and Progress towards Vibrational ERE-CARS Measurements in High-Pressure Flames

摘要

Stereo Particle Image Velocimetry measurements are reported in a new counter-flow burner. The measurements indicate that the burner produces axi-symmetric, top hat velocity profiles over the central 8 mm at the nozzle exit. N_2 CARS will be employed to obtain temperature profiles in counter-flow methane and hydrogen flames in the near future. We also report the progress towards restoration and upgrade of a high-pressure flame facility. Subsequently, vibrational ERE-CARS measurements of NO concentration will be performed in this facility at pressures up to 10 atm.
