Computational Engineering Sciences:   The CFD Laboratory graduate research focus emphasis has been fundamental theory developments in modified continuous Galerkin weak form methods. The goal has been generation of linear basis finite element discrete implementations exhibiting the accuracy/converge attributes the domain of higher degree basis constructions. The linear basis finite spatial semi-discretization is ultimately most efficient in parallel computing. Pivotal archival publications include:

    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 for closure. Wavenmuber asymptotics with approximate deconvolution achieves analytical PDE closure for three of the four tensors/vectors. The optimal modified continuous Galerkin theory provides analytical closure replacing the wavenumber theory insignificant subfilter scale (SFS) tensor/vector. Implementation of this theory in parallel computing practice for validation is the dissertation topic of Mr. Sekachev.
