Abstract
The effect of a statistically anisotropic distribution of stretched vortices in the Lundgren-Townsend model of the fine-scale structure of homogeneous turbulence is considered. Lundgren's argument that anisotropy does not affect the three-dimensional energy spectrum is confirmed. Examples of velocity derivative moments and one-dimensional vorticity spectra are worked out for the case of an axisymmetric probability distribution. It is found that scaling of three-dimensional vorticity spectra may not be visible in the one-dimensional spectra.
