This figure shows the influence of the Reynolds number on the turbulent development of transitional, isothermal subsonic round jets and on their radiated noise. The Mach number of the jets is 0.9, and their Reynolds 
numbers are: (a) 1,700; (b) 2,500; (c) 5,000 and (d) 400,000. The flow and the acoustic fields are calculated directly using compressible Large Eddy Simulations. The vorticity norm is represented in the jet flow, 
and the fluctuating pressure is visualized outside..
