Abstract
This paper presents the mean velocity field for co-swirling co-axial j ets mixing in a dump confinement. The velocity ratio between the outer jet and the inner jet was 1.667. The velocity measurements were taken with the help of a 3-hole pressure probe operated in null mode. Measu red flow field shows a significant effect of variation of the swirl va lue in both the jets. A blown-off reverse flow zone forms on the symme tric axis for certain combinations of swirl value in the two jets.
