Turbulent JP-8 Flames: Concentration and Temperature Profiles to Assess a Chemistry Mechanism

Abstract

The chemistry that occurs at when JP-8 fuel is burned at extreme turbulence levels, corresponding to turbofan engines and augmenters, was studied using laser diagnostics. A new Distribu-burner was constructed in order to increase the reactant temperature to 1500K. Properties of JP-8 highly preheated premixed turbulent flames were measured. Lasers were operated to fluoresce and detect three fuel components of JP-8 fuel: toluene, napthalene and tri-methyl benzene. Large amounts of dilution with inerts (product) gases were added to lower the oxygen content of the oxidizer from 21% to 6% to achieve enginelike conditions. Results have been compared to DNS computer simulations of distributed combustion.
