Large-eddy simulation of separation and transition for turbomachinery flows,eddy simulation require the solution of a Poisson equation for pressure, which is frequently the main source of computational expense in simulations within complex boundaries. Marked computational advantages are described for a flow which is periodic in one dimension through the use of Fourier techn

Symmetry-preserving discretisation for direct numerical simulation of turbulence,ic, positive definite. Such a symmetry-preserving discretisation is used to perform a direct numerical simulation of a fully developed turbulent flow in a channel, where a matrix of cubes is mounted at one wall of the channel. The Reynolds number (based on the channel width and the mean bulk velocit

Aircraft wake vortices in the atmosphere,ate and (ii) about optimized separation distances between aircraft landing at an airport for possibly increasing its capacity. To this end, large-eddy simulations have been performed to learn about the behaviour of vortex wakes shed by cruising aircraft in the free atmosphere and in the atmospheric

Output bound approximations for partial differential equations; application to the incompressible nrtial differential equations. The general theory is presented, and earlier applications of the procedure to a variety of different problems—including the Poisson equation, the advection-diffusion equation, elasticity problems, the Helmholtz equation, the Burgers equation, and eigenvalue problems—are

Large-eddy simulation of the flow over a matrix of surface-mounted cubes,nd different grid resolutions are performed. Mean velocities, Reynolds stresses, and Strouhal number are evaluated and compared with available experimental data. In general the LES results agree well with the experiment. Finally, the present results are compared with previous single-cube LES computa

A study of built-in filter for some eddy viscosity models in large-eddy simulation,etries are restricted. This is mainly due to the physical hypotheses of homogeneity, isotropy, or local equilibrium of the subgrid-scale models, which are questionable in more realistic configurations. In an attempt to overcome those problems, the recent notion of Very Large-Eddy Simulation (VLES) h
