Stating that "the turbulence kinetic energy is dissipated into heat." seems thermodynamically wrong. The kinetic energy is rather transformed to thermal energy, i.e., the temperature of the fluid increases. This may or may not result in heat transfer, depending on the boundary conditions. — Preceding unsigned comment added by Alexander.mitsos (talk • contribs) 09:29, 20 April 2023 (UTC)

- I noted the video added to the Kolmogorov microscales article. I am not sure the CFD visualizations are clear enough to help an average reader. I am inclined to remove it, but would like your assessment of how it helps. There are important graphics needed for this article. A contrast between two different 2D CFD simulations with different Kolmogorov microscales could be very useful. Gavoth (talk) 21:39, 25 March 2024 (UTC)
- I believe the video is completely irrelevant and does not illustrate the microscales themselves. Also, a 2D simulation cannot ever accurately simulate turbulence. Turbulence is inherently a 3D phenomenon. At least that kind of turbulence where Kolmogorov microscales are relevant.
- Proper 3D direct numerical simulation illustrating different scales in the flow at different (e.g.) Reynolds numbers would make sense, but hardly this. Spectra would also be helpful. Vladimír Fuka (talk) 14:06, 22 November 2024 (UTC)
