Abstract	Test data is presented which allows determination of jet penetration and mixing of multiple cold air jets into a ducted subsonic heated mainstream flow. Jet-to-mainstream momentum flux ratios ranged from 6 to 60. Temperature profile data is presented at various duct locations up to 24 orifice diameters downstream of the plane of jet injection. Except for two configurations, all geometries investigated had a single row of constant diameter orifices located transverse to the main flow direction. Orifice size and spacing between orifices were varied. Both of these were found to have a significant effect on jet penetration and mixing. The best mixing of the hot and cold streams was achieved with spacing between the orifices equal to one half of the duct height. For this spacing, variation in orifice size changed the mean exit temperature level, but did not significantly alter the shape of the distributions. The mixing at the various test conditions was evaluated using an energy exchange parameter developed in this program. Comparison of the results of this study with existing single jet data indicates that single jet correlations do not adequately describe the multiple jet results.
