Reinhard M?rz,Christoph W?chterarried out. These models are not based on the classical Fickian approximation and do not induce necessarily an alignment between the SGS heat flux vector and the gradient of the resolved temperature..Six SGS models are investigated, on two grids. The results are compared with DNS results obtained by Kawamura . [2].

The Global Positioning System (GPS)omplex flows when using nonuniform filter-widths are analysed in some detail. The magnitudes of discretisation and modelling errors arising in a turbulent mixing layer are determined and their interaction is shown to lead to partial cancellation of errors for various spatial discretisation methods.

Chinese Navigation Satellite Systemsions (LES). There are various candidates for the subgrid-scale modeling used in LES. A preliminary examination of the role of temporal and spatial variability of the eddy viscosity and diffusivity used in such models is presented here. A specific comparison between the Smagorinsky model and a simpli

The Adams-Bashforth scheme is used for time marching integration and a QUICK difference is used for space discretization on a staggered grid for the 3D Navier-Stokes equations..As a test case, a turbulent isothermal jet is ca
