Index of /turbdata/HST/stats/spectra
Files in this directory contain 1D and 2D spectra extracted from
direct numerical simulations of statistically-stationary homogeneous
shear turbulence. Only three cases are given, i.e., Re_lambda=100
with aspect ratios (Axz,Ayz)=(3,2) and (3,4), and Re_lambda=250
with (Axz,Ayz)=(3,2).

Spectra for u, v, w, omegax, omegay and omegaz and cospectra for uv
are given. Take the spectra of u for example, Euu_x means spectra
in the streamwise direction, while Euu_z for the spanwise direction
and Euu represents 2D spectra. Note that spectra contains the zero
mode, while wave number kx & kz start from 2pi/Lx and 2pi/Lz
respectively. The wave length can be easily obtained from wave
nuumber and they can be normalized by either eta (Kolmogrov scale)
or Le (integral scale) in the file.
