Hydrodynamic and hydromagnetic energy spectra from large eddy simulations

Direct and large eddy simulations of hydrodynamic and hydromagnetic turbulence have been performed in an attempt to isolate artifacts from real and possibly asymptotic features in the energy spectra. It is shown that in a hydrodynamic turbulence simulation with a Smagorinsky subgrid scale model using 5123 mesh points, two important features of the 40963 simulation on the Earth simulator Y. Kane...

Large Eddy Simulations using oodlesDST

The oodlesDST code is based on OpenFOAM software and performs Large Eddy Simulations of turbulent fluid flows. The code contains a number of specialized subgrid scale turbulence models and wall models. This report describes these models in sufficient detail to allow a new user of the code to make informed decisions regarding the use of these models for particular applications. An overview of th...

Large-Eddy Simulations of Turbulent Flows, from Desktop to Supercomputer

In this paper, a general introduction to the large-eddy simulation (LES) technique will be given. Modeling and numerical issues that are under study will be described to illustrate the capabilities and requirements of this techniques. A palette of applications will then be presented, chosen on the basis both of their scientific and technological importance, and to highlight the application of L...

Physical Bias of Galaxies From Large-Scale Hydrodynamic Simulations

We analyze a new large-scale (100hMpc) numerical simulation of the popular ΛCDM cosmological model including in our treatment dark matter, gas and galaxies formed on the basis of standard physical processes. The method, applied with a numerical resolution of < 200hkpc (which is small compared to nearest neighbor separation of galaxies except in clusters), attempts to determine where and when ga...
