Gj. Sturgess et al., LEAN BLOWOUT IN A RESEARCH COMBUSTOR AT SIMULATED LOW-PRESSURES, Journal of engineering for gas turbines and power, 118(4), 1996, pp. 773-781
A propane-fueled research combustor has been designed to represent the
essential features of primary zones of combustors for aircraft gas tu
rbine engines in an investigation of lean blowouts. The atmospheric pr
essure test facility being used for the investigation made it difficul
t to approach the maximum heat release condition of the research combu
stor directly. High combustor loadings were achieved through simulatin
g the effects on chemical reaction rates of subatmospheric pressures b
y means of a nitrogen diluent technique. A calibration procedure is de
scribed, and correlated experimental lean blowout results are compared
with well-stirred reactor calculations for the research combustor to
confirm the efficacy of the calibration.
