Systematic measurements of OH chemiluminescence for fuel-lean, high-pressure, premixed, laminar flames

摘要

Systematic measurements are reported of OH chemiluminescence from a premixed laminar flame at pressures and equivalence ratios ranging from 0.5 to 2.5 Mpa and 0.66 to 0.86, respectively. The objective was to obtain non-existent experimental data and to determine the viability of using OH chemiluminescence as an active-control parameter for high-pressure, premixed flames. The signal from the first electronically excited state of OH to ground (at 305.4 nm) was detected through a band-pass filter with a photo-multiplier tube.
