Abstract
The one‐dimensional equilibrium spectra in isotropic turbulence are given for the physical transfer theories of Heisenberg, Kovásznay, and Obukhoff. These results are then compared with the experimental measurements of the spectrum of ∂3u1/∂x13 fluctuations. For two of the theories (Heisenberg's and Kovásznay's), reasonable agreement is obtained for kη < 0.04, but for larger values of kη there is considerable divergence between the theoretical and experimental results. The relationship between the equilibrium and similarity spectra are also discussed for these two theories.Keywords
