要約
The evidence of inverse spectral energy transfer in turbulent round jet is presented via Large Eddy Simulation with constant Smagorinsky model. Numerical simulation has been performed for wide range of Reynolds numbers and with applying low-amplitude inlet fluctuations and swirl. By varying these parameters, it has been possible to investigate the influence of different vortex stretching patterns on the amplitude and sign of spectral energy flux in the near region of the jet.
