The mean velocity field of turbulent free jet issuing from the multiple rectangular nozzles which are arranged in line has been investigated, experimentally. The aim of this study is to examine characteristics of the mean velocity field of the multiple rectangular jets with constant nozzle pitch aspect ratio S/L (=1.00) which is the ratio of the nozzle arrangement pitch S/d to the nozzle aspect ratio L/d. Four nozzle arrangement pitches used in this study were 6.25, 12.50, 18.75 and 25.00. The Reynolds number based on the nozzle width d and the exit mean velocity Ue was kept constant 25000, throughout this experiment.
