OPEN-LOOP CONTROL OF SWIRL-STABILIZED SPRAY FLAMES

There is a considerable amount of work in the area of active combustion control

of gaseous combustion (see [1, 2] for recent reviews on this topic). The majority

of these studies have dealt with a blu-body-stabilized combustor or a dump

combustor where the recirculation induced by a blu body or by a sudden ex-

pansion is used to stabilize the ame. Active control strategies have been used

to primarily suppress thermo-acoustic instabilities resulting from a coupling be-

tween the heat release and the acoustic modes in the combustor. These control

so

gies have also looked at improving fuel eÆciency and reducing pollutants [3], and

in extending ammability limits [4].
