1301.6249 (Ran Zheng et al.)

One-dimensional energy spectra in three-dimensional incompressible
homogeneous isotropic turbulence

Ran Zheng, Wang Yao-yao, Yuan Xing-jie
The paper investigates the detailed features of one-dimensional energy spectra in three-dimensional isotropic turbulence, based on the exact solution of Karman-Howarth equation. Particular interest will be paid on the degree to which spectral scaling can lead the spectral data to be collapsed. The theory appears to be consistent with the wealth of experimental data (G.Comte-Bellot and S. Corrsin, 1971) at least in low Taylor microscale Reynolds number.
