Applications of the nonlinear galerkin methods to some flow problems,Different non-linear Galerkin algorithms are compared with respect to each other in terms of convergence and efficiency. The improvements with respect to classical Galerkin spectral method are shown numerically. The method seems to be promising in the context of the direct numerical simulation of the Navier-Stokes equations.

Large eddy simulation of high reynolds number circular cylinder flow,ing the free shear layers in which transition takes place. The results were carefully evaluated and compared with available experimental data. In general, the LES results agreed fairly well with measurements.

Scaling in wall-bounded shear turbulence,l difference between POD modes and other standard orthogonal functions such as Fourier modes, Tchebichev polynomials, etc. is the derivation of the modes themselves. We show here that POD modes of a turbulent channel flow can be well approximated by a Sturm-Liouville system.

Insights for LES from structure-based turubulence modeling,non-equilibrium flows. Some of the most important shortcomings of standard one-point eddy-viscosity and Reynolds Stress Transport (RST) models are caused by the lack of structure information in these models. In Large Eddy Simulations (LES) local homogeneity is usually assumed by most sub-grid scale
