... Abstract A new method for implementation of wall-modeled large eddy simulation (WMLES) for use with high-order spectral element methods is introduced. Spectral element methods present unique challenges for wall modeling, specifically related to the application of appropriate wall boundary...

... generation mechanisms associated with a rotating small axial fan using high-resolution large-eddy simulation. The computed results present the first mode of blade passing frequency and its harmonics although there is slight difference in the frequency. Using the data obtained, data analyses are carried out...

... of cavity are placed on the fixed wall. The objectives are to study the aero acoustic capabilities of LBM and to build and to assess the efficiency of the Lattice Boltzmann Equation (LBE) as a new computational tool to perform the Large-Eddy Simulations (LES) for turbulent flows. In the first part...

..., and implicit large-eddy simulation (ILES) often becomes the effective strategy. We focus on ILES initialized with well-characterized 256 3 homogeneous isotropic turbulence datasets generated with direct numerical simulation (DNS). ILES is based on the LANL xRAGE code, and solutions are examined as function...

... Abstract In this study, unsteady flow simulations using a large-eddy simulation are conducted to analyze vehicle aerodynamics. The objective is to investigate flow structures that cause unsteady lift fluctuations potentially affecting the drivability of a vehicle. In addition, the dependence...

... to several kilometers. In the solver, we adopt the immersed boundary method and the Lagrangian dynamic large-eddy simulation model and extend them to atmospheric flows. The computations are accelerated on GPU clusters with a dual-level parallel implementation that interleaves MPI with CUDA. We evaluate...

... 10 07 2009 Particle transport and deposition in a turbulent channel flow simulated by the Large Eddy simulations (LES) were studied. Particular attention was paid to the effect of subgrid scales (SGS) turbulence fluctuation on particle motion. Finite volume method was used for finding...
