• Mean flow properties of air jet issuing from the cruciform nozzle with a sufficiently large aspect ratio into still air have been observed over a wide area of the flow field. From the experiment, it is clear that the streamwise variation of the both scales of velocity and length is slower than that of two-dimensional and axi-symmetric jets. The velocity contours show a symmetric, crisscross shape even at the most downstream section measured in this experiment, whilst in the upstream region the velocity profile exhibits a saddle-back shape for both symmetric slices of y = 0 and z = 0. In the region of x/d≧75 the velocity profiles can be expected to be geometrically similar in the entire flow field.
