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 cylinderbody 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.
