Gj. Sturgess et al., EFFECTS OF BACK-PRESSURE IN A LEAN BLOWOUT RESEARCH COMBUSTOR, Journal of engineering for gas turbines and power, 115(3), 1993, pp. 486-498
Experimental information is presented on the effects of back-pressure
on flame-holding in a gaseous fuel research combustor. Data for wall t
emperatures and static pressures are used to infer behavior of the maj
or recirculation zones, as a supplement to some velocity and temperatu
re profile measurements using LDV and CARS systems. Observations of fl
ame behavior are also included. Lean blowout is improved by exit block
age, with strongest sensitivity at high combustor loadings. It is conc
luded that exit blockage exerts its influence through effects on the j
et and recirculation zone shear layers.
