On the Stolz–Adams deconvolution model for the large-eddy simulation of turbulent flows. (English) Zbl 1128.76029
Summary: We consider a family of large-eddy simulation (LES) models with an arbitrarily high consistency error for 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 , where is the model’s solution and is the true flow averages.
