Mixing indices describing the completeness of mixing between pairs of plane jets in a triple coflowing jet array have been measured using marker nephelometry. This work is an extension of the results reported by Grandmaison and Zettler (1989) for the case where the centre jet in the array has a higher velocity than the adjacent outer jets. Results include centreline measurements of the static pressure, mean velocity and mean and fluctuation concentration fields, as well as transverse measurements of these properties and concentration intermittency in the near field region where there is significant mixing between the jet streams.
