The turbulence intensity in the exit jet was measured using a
TSI 1210-T1.5 miniature hot wire probe with 3.8 lm diameter. The same computer-controlled traverse system was used to mea-
sure at several points from the nozzle edge to the centre in a single run. Fig. 12 shows the distribution of the turbulence intensity

removed. In this con guration noise tone produced by vortex shed- ding past the airfoil trailing edge is expected. The experiment was
carried out at jet speed vj of 80 m/s and the measured noise
predicted airfoil noises. At this speed, the measured airfoil noise is still at least 10 dB above the background noise for all the frequencies. The deviation between the Brooks et al.’s trailing edge noise predic- tion to the measured airfoil noise below 2 kHz is caused by the airfoil leading edge and the facility noises bein
