Media type: E-Article Title: On the use of the notion of suitable weak solutions in CFD Contributor: Guermond, Jean‐Luc imprint: Wiley, 2008 Published in: International Journal for Numerical Methods in Fluids Language: English DOI: 10.1002/fld.1853 ISSN: 0271-2091; 1097-0363 Origination: Footnote: Description: <jats:title>Abstract</jats:title><jats:p>The notion of suitable weak solutions for the three‐dimensional incompressible Navier–Stokes equations together with some standard regularization techniques for constructing these solutions is reviewed. The novel result presented in this paper is that Faedo–Galerkin weak solutions to the Navier–Stokes equations are suitable provided they are constructed using finite‐dimensional spaces having a discrete commutator property and satisfying a proper inf–sup condition. Low‐order mixed finite element spaces appear to be acceptable for this purpose. Connections between the notion of suitable solutions and LES modeling are investigated. A proposal for a large eddy scale model based on the notion of suitable solutions is made and numerically illustrated. Copyright © 2008 John Wiley & Sons, Ltd.</jats:p>
