HOM24

Direct numerical simulation of Homogeneous shear flow. 

From Sarkar, S. 1995 J. Fluid Mech., 282, 163-186.

File velocity.dat: ASCII file
------------------------------
Evolution of various quantities, as a function of dimensionless time, St.

Columns 1-8  contain:
   St  K epsilon  b11  b22  b12  SK/epsilon Relambda

Here, S is the mean shear rate, K is the turb. kinetic energy, epsilon the 
turbulent dissipation rate, and
bij = <ui uj>/2K - (1/3)deltaij is the anisotropy tensor.
The nondimensional viscosity is nu = 1/200.
Relambda is the microscale Reynolds number defined by 
  Relambda = sqrt[ 10*K/(epsilon*nu) ]

File length.dat: ASCII file
---------------------------
Evolution of integral lengths as a function of dimensionless time, St.

col. 1 is St, col. 2 is l_x(uu), col. 3 is l_x(vv), col. 4 is l_x(ww). 

where l_x(uu) is the integral scale associated with <u u(x)> , etc.


File spectra.dat: ASCII file
---------------------------
Three-dimensional energy spectra of the fluctuating velocity, at 
 dimensionless times   St=0,3,5,7,9,11,13,15

col. 1 is the wavenumber k, col. 2 is the spectrum; both in 
   computational units.


Directory correlation: Binary files of two-point correlations
-------------------------------------------------------------

The files mentioned below contain two-point correlation data in
IEEE single precision format as a function of the separation vector 

R_ab(id,jd,kd) = a(i,j,k)*b(i+id,j+jd,k+kd) 

averaged over the whole flow volume,  where id,jd,kd=0..32.
