investigated using hot-wire anemometry. The data include distributions of the mean and
high order turbulence moments over 8000< Re< 50 000 along the jet centreline. It is
demonstrated that the far-field rates of the mean velocity decay and spread, as well as the
asymptotic value of the streamwise turbulent intensity, all decrease as Re increases for Re≤
30 000; however, they become approximately Re-independent for Re> 30 000. It follows that …
