An experimental study of the flow field from an array of rectangular jets has been conducted. The measurements include the total pressure field and the streamwise component of the turbulence field using hot wire anemometry. The mapping of these quantities is quite complete in the region within 30 jet slot widths of the nozzle exit plane. Experiments have been conducted at nominal Reynolds numbers of 22900 and 10000, based on nozzle slot width. The jets first appear to develop in a fashion comparable to that for a single free rectangular jet. Eventually, at a distance which depends upon the interjet specing, the jets merge. (Kursetz)
