Special Issue: Direct and Large Eddy Simulation

High performance computation for direct numerical and large eddy simulation

This paper focusses on high order compact schemes for direct numerical simulation (dns) and large eddy simulation (les) for flow separation, transition, tip vortex, and flow control. We discuss the fundamental issues of high quality grid generation, high order schemes for curvilinear coordinates, the cfl condition for complex geometry, and high-order weighted compact schemes for shock capturing...

Applied large eddy simulation.

Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier-Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role. However, the improvement in accuracy and flow d...

Adaptive Large Eddy Simulation

This project is focused on development of a novel approach, called Stochastic Coherent Adaptive Large Eddy Simulation (SCALES) for modeling and simulation of turbulent flows. The approach comes from the realization of the deficiency of the current Large Eddy Simulation (LES) approach, which resolves only the large-scale motions instead of coherent energy containing flow structures. The SCALES a...

Temporal Large-Eddy Simulation

In 1999, Stolz and Adams [Phys. Fluids 11 (1999)] unveiled a subgrid-scale model for LES based upon approximately inverting (defiltering) the spatial grid-filter operator and termed .the approximate deconvolution model (ADM). Subsequently, the utility and accuracy of the ADM were demonstrated in a postenon analyses of flows as diverse as incompressible planechannel flow and supersonic compressi...
