An experiment was carried out on the flow around a dual jet which is issued from two parallel slot nozzles set on a common end wall and is mixed turbulently with the ambient air. Distribution of cavity pressure, that of mean and fluctuating velocities, shape of the jets and cavity length were determined. From these measurements, the effect of distance between the nozzles on the flow field was studied and the following results were obtained : (1) Two jets attract each other and the axis of a jet coincides with an arc of a circle. (2) Except in the case of small distance between two nozzles, the radius of the jet axis and the cavity length increase in proportion to the nozzle distance. (3) Except in the region near the nozzle and the junction of two jets, momentum flux of the jet in flow direction is conserved.
