Abstract

Recent subgrid models for large-eddy simulations of turbulent hows are evaluated, particularly the dynamic-Smagorinsky combination, with emphasis on identifying the reasons for their success and the limits of their applicability. The argument is made that they reproduce the turbulent dissipation relatively well, but their main advantage is that they are robust to errors in that they have a built-in mechanism to adjust the dissipation without substantially modifying the larger scales. The question of the stresses is considered next. It is found that it is an intrinsic property of subgrid models that the stresses are essentially unpredictable, and the models considered are indeed found not to reproduce them correctly, even on the average. In particular, the stress-strain correlation is low in real turbulence, and because eddy viscosity models assume that both are proportional, they always result in either the wrong energy spectrum or the wrong stresses. This is confirmed by simulations of shear flows, where it is shown that the error of the mean how can only be made small if the subgrid stresses are negligible. Stresses are however large-scale quantities that are carried by the resolved scales if the resolution is fine enough. Explicit limits are given.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-02:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 58.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 58 (PlumX).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
