directions of radiation of these four noise components based on the analysis above. Overall, the noise of the large turbulence
structures and the new noise component are the most dominant. Both components have nearly equal maximum noise
intensity. The new noise component is dominant in the directions from about 1001 to 1301. Its intensity peaks around 1151.
The large turbulence structures noise,on the other hand,is dominant in the directions of 1101 to 1501, peaking around 1351
to 1401. Other than these two most dominant noise components,the fine-scale turbulence noise is important for radiation in
the upstream direction .In the downstream direction at inlet angles 1351 and larger,there is a very low-frequency unknown
noise component. Because the available data covers only directions up to 1501, we are unable to offer further information on
this unknown noise component at angles closer to the jet flow direction.
