! Last updated 09/08/2008 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 PhysFluids_19_105111_ChangMoser2007.pdf - the Physics of Fluids paper readme2.txt - this file Tijk_define.pdf - more detailed documentation Contact Information: Robert D.
