On the Stolz--Adams deconvolution model for the large-eddy simulation of turbulent flows. (English)
[J] SIAM J. Math. Anal. 37, No. 6, 1890-1902 (2006). ISSN 0036-1410; ISSN 1095-7154/e

Summary: We consider a family of large-eddy simulation (LES) models with an arbitrarily high consistency error $O(\delta^{2N+2})$ for $N = 1,2,3,\ldots$ that are based on the van Cittert deconvolution procedure. This family of models has been proposed and tested for LES with success by Adams and Stolz in a series of papers, e.g., [Deconvolution methods for subgrid-scale approximation in large-eddy simulation, in: Modern Simulation Strategies for Turbulent Flow, R. T. Edwards, Philadelphia 2001, 21--41 (2001), An approximate deconvolution procedure for large eddy simulation, Phys. Fluids A 11, 1699--1701 (1999)]. We show that these models have an interesting and quite strong stability property. Using this property we prove an energy equality, existence, uniqueness, and regularity of strong solutions and give a rigorous bound on the modeling error $\left\|{\overline{u}-w}\right\|$, where ${\bold w}$ is the model's solution and $\overline u$ is the true flow averages.
