This readme file is associated with the Physics of Fluids paper entitled
"An inertial range model for the three-point third-order velocity
correlation," by Chang and Moser (2007). The material here provides the
complete definition of the inertial range 3-point 3rd-order correlation,
along with example software designed to evaluate the model. For further
details see the documentation in Tijk_define.pdf, and comments in the files.
Also check for possible updates at http://turbulence.ices.utexas.edu
The files included here are as follows:
basisdata.txt - contains the data describing the 5 basis functions for
the correlation model, standard form
basisdata_asympf2.txt - contains the data describing the 5 basis functions for
the correlation model, asymptotic form for small s
evalTijk.f90 - module of subroutines and functions including those below:
subroutine read_basis - reads in basis function data,
e.g. from "basisdata.txt"
subroutine build_composite - given coefficients of the basis
functions, sets up composite function (model)
double precision function eval_composite - evaluates the model for
given component (i,j,k) and
separation (r,s), returning
the value of the correlation
evalTijk_asymp.f90 - new version of module evalTijk.f90 which includes
asymptotic forms for small separations
eval_2pt_3or_tophat.f90 - example program using evalTijk.f90 to evaluate
the correlation and it's integral (filter)
eval_2pt_3or_tophat.txt - example output from eval_2pt_3or_tophat.f90
eval_2pt_3or_tophat_asymp.f90 - example program using evalTijk_asymp.f90 to
evaluate the correlation and it's integral (filter)
eval_2pt_3or_tophat_asymp.txt - example output from eval_2pt_3or_tophat_asymp.f90
