Architecture of Approximate Deconvolution Models of Turbulence*ct energy balance implies correct prediction of turbulent statistics. Interestingly, the approach is simple and thus gives a road map to develop models for more complex turbulent flows. We illustrate this herein for the case of MHD turbulence.

Analysis of Truncation Errors and Design of Physically Optimized Discretizations, analysis, and optimization of nonlinear discretizations. Implicit LES can be made rigorous by requiring that the numerical dissipation approximates the SGS dissipation obtained from the analysis of nonlinear interactions in turbulence.

Analysis of Numerical Error Reduction in Explicitly Filtered LES Using Two-Point Turbulence Closuresh cut-off wavenumber are responsible for a major part of the differentiation errors. In addition, the accuracy of a LES calculation is seen to be improved when explicit filtering of the higher part of the turbulence spectrum is introduced.

Large Eddy Simulation of Atmospheric Convective Boundary Layer with Realistic Environmental Forcingsd evolution as compared to observational data. Effects of initialization errors on simulated features of the CBL for different evolution patterns of daytime environmental atmospheric flow are analyzed. Possible approaches toward dynamic adjustment of environmental parameters in LES of atmospheric boundary layer flows are suggested.

Anisotropic Grid Refinement Study for LES grid refinement in different directions has an effect differing both in manner and magnitude. This differing manner is highlighted in the various behaviours of the Reynolds stress components. The index of resolution quality was found to be misleading, since it can underestimate the relative importance of the grid refinement effects.
