Abstract: An experimental study has been conducted to examine the low-speed
aerodynamic characteristics of a pair of circular jets behaviour in the
vortex-wake of a blunted cone cylinder-body combination with and without a 70°
leading edge sweep delta wing. The induced flow-field was examined via
two-dimensional hot-wire anemometry surveys. Comparisons were made between the
induced wake with and without the circular jets. The flow field over the models
was visualized using smoke and oil flow visualization. The jet-pair was found
to undergo severe distortion within a very short distance from the nozzle
exits. The shape of the jets was shown to change considerably when placed in
the vortex wake flow field of the models, which caused the jet-pair to spread
and become entrained within the vortices and wake created by the models.
