Effects of turbulence of species mass factions in methane/air jet flames

摘要

It is important that combusiton models capture the effects of turbulent miing on reaction zone structure in non-premixed and partially premixed flames.A more complete understanding of the response of species mass fractions to turbuen t mixing is needed to imporve predictive capabilityties,paicularly with regard to combustion intermediates and minor species.usinghthe combinatin of Raman scattering,Rayleigh scattering,and laser-inducd fluorescence,simulaineous measruements of CO,OH,H_2 and NO are obtianed along with the major sepcies temeprature,and mixture framtion in a series of xsix piloted methane/air jet flames.
