摘要: ABSTRACT Chemiluminescence from species such as CH*, C2*, OH* and CO2* often are used a quantitative diagnostic in experimental studies of premixed combustion. This paper reports results numerical investigation chemiluminescence laminar turbulent flames. Calculations carried out using complex reaction mechanism for methane propane model chemiluminescence. Relationships between chemiluminescent intensity both H-atom concentration heat release rate quantified functions dilution, equivalence ratio, steady unsteady strain-rate. These relationships monotonic, but not unique; they depend on which flame parameter is varied. However, the effect unsteadiness relationship strained negligible, this allows use chemiluminescence-based diagnostics measurement relative rates fl...
