Investigation of Non-Premixed Opposed Flow H_2/Air Laminar Flames using Coherent Anti-Stokes Raman Scattering (CARS)

摘要

Temperature profiles have been obtained along the centerline of non-premixed opposed flow H_2/Air flames using two counter-flow burners. The measurements were performed at varying strain rates but with fixed fuel and oxidizer composition to study the effect of strain rate on peak temperature and temperature profile shape. In addition, a qualitative study was conducted over a large range of strain rates, including unsteady regime, to investigate flame structure. Photographs of flames corresponding to some temperature profiles have also been included.
