The results from a ducted combustion test program on supersonic
mixing and combustion enhancement are presented. The test was
conducted in a scramjet combustor using aerated (by air or hydro-
gen) liquid kerosene (eervescent) jets injected through elliptic noz-
zles from tube-micropylons and n-pylons. Kerosene jets were injected
into a two-dimensional diverging-area supersonic combustor in two ways:
(1) through nozzles drilled in tube-micropylons at an angle of 45
Æ
rela-
tive to the main-stream air ow direction and (2) through nozzles drilled
at the base of n-pylons. In the latter case a co-ow injection was used.
