Permanent three-dimensional patterns in turbulent flows with essentially two-dimensional wall configurations.

Type of article: Article

Summary

The observed permanent and periodic two-dimensional temperature and wall-pressure distributions and three-dimensional flow structures in turbulent flows with two-dimensional obstacles are all of the same order of magnitude of wavelength. This leads to the hypothesis that the same physical mechanism is responsible for these different phenomena. No physical explanation of the origin of this phenomenon and of the observed dependencies on the wavelength are available yet.
