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.
