    Turbulence closure for CFD:   Spatial filtering of the thermal Navier-Stokes conservation principles PDE system leads to a theory-identified quadruple of Reynolds stress tensors/heat flux vectors requiring identification. Newly developed research employs wavenmuber asymptotics with approximate deconvolution to achieve analytical closure, replacing the insignificant subfilter scale (SFS) tensor/vector with a weak form continuum theorization. The recent publication on this exciting new CFD topic is:

    • "Analytical SFS Tensor/Vector Closure Model for Rational LES Thermal Navier-Stokes,” A.J. Baker, M.R. Grubert & J.A. Orzechowski, J. Numerical Methods in Fluids, V. ,revision in review, 2009.
