THE PRIMARY OBJECTIVE IS TO APPLY THE WIENER-HERMITE METHOD TO STATISTICALLY HOMOGENEOUS, ANISOTROPIC TURBULENT FLOWS WHICH ARE APPROACHING ISOTROPY IN THE ABSENCE OF MEAN SHEAR OR STRAIN.

THE PRIMARY OBJECTIVE IS TO APPLY THE WIENER-HERMITE METHOD TO STATISTICALLY HOMOGENEOUS, ANISOTROPIC TURBULENT FLOWS WHICH ARE APPROACHING ISOTROPY IN THE ABSENCE OF MEAN SHEAR OR STRAIN. THE UNIQUENESS OF THE APPROACH LIES IN THE FACT THAT REYNOLDS NUMBERS OF PRATICAL INTEREST WILL BE USED, A FEAT WHICH SHOULD BE EASY TO ACCOMPLISH WITHIN THE FRAMEWORK OF THE WIENER-HERMITE METHOD. NUMERICAL SIMULATION OF THREE DIFFERENT APPROACH-TO-ISOTROPY FLOWFIELDS IS PROPOSED. DETAILED COMPARISONS WITH EXPERIMENTAL DATA WILL BE MADE TO ASSESS ACCURACY OF THE WIENER-HERMITE EXPANSION. COMPUTATIONS WILL BE ACCOMPLISHED WITH A MODIFIED VERSION OF AN EXITING PROGRAM WHICH EMBODIES THE METHOD FOR ISOTROPIC AND HOMOGENEOUS TURBULENCE. AS A SECONDARY OBJECTIVE, THE FEASIBILITY OF EXTENDING THE METHOD TO HOMOGENEOUS, ANISOTROPIC TURBULENCE IN THE PRESENCE OF UNIFORM SHEAR AND/OR STRAIN WILL BE ASSESSED. THE PRIMARY CONSIDERATION WILL BE ESTABLISHING THE AMOUNT OF COMPUTING TIME NEEDED FOR SUCH COMPUTATIONS.
