Advances in large eddy simulation methodology for complex flows
TL;DR: A review of the recent advances in the derivation of the constitutive equations for large eddy simulation, subgrid scale modeling, wall modeling and applications of LES to turbulent combustion focuses on a review of two numerical methods for LES in complex geometry.

Grid-independent large-eddy simulation using explicit filtering
TL;DR: By using explicit filtering in large-eddy simulation, turbulent statistics and energy spectra are shown to be independent of the mesh resolution used.

Dynamic slip wall model for large-eddy simulation.
TL;DR: A dynamic procedure for the slip coefficients is formulated, providing a dynamic slip wall model free of a priori specified coefficients that alleviates the well-known problem of the wall-stress under-estimation by current subgrid-scale (SGS) models.

Christopher J. Keylock,Richard J. Hardy,Daniel R. Parsons,Robert I. Ferguson,Stuart N. Lane,Keith Richards +5 more
TL;DR: Large-eddy simulation (LES) is a method for resolving the time-dependent structure of high Reynolds number, turbulent flows as discussed by the authors, and it is possible to model and track the behaviour of coherent turbulent structures and study their effect on the flow field.

A dynamic subgrid‐scale eddy viscosity model
TL;DR: In this article, a new eddy viscosity model is presented which alleviates many of the drawbacks of the existing subgrid-scale stress models, such as the inability to represent correctly with a single universal constant different turbulent fields in rotating or sheared flows, near solid walls, or in transitional regimes.

Factoring wavelet transforms into lifting steps
Ingrid Daubechies,Wim Sweldens +1 more
TL;DR: In this paper, a self-contained derivation from basic principles such as the Euclidean algorithm, with a focus on applying it to wavelet filtering, is presented, which asymptotically reduces the computational complexity of the transform by a factor two.

The Lifting Scheme: A Custom-Design Construction of Biorthogonal Wavelets
TL;DR: In this paper, a lifting scheme is proposed for constructing compactly supported wavelets with compactly support duals, which can also speed up the fast wavelet transform and is shown to be useful in the construction of wavelets using interpolating scaling functions.
Journal ArticleDOI
The lifting scheme: a construction of second generation wavelets
TL;DR: The lifting wavelet as discussed by the authors is a simple construction of second generation wavelets that can be adapted to intervals, domains, surfaces, weights, and irregular samples, and it leads to a faster, in-place calculation of the wavelet transform.
