Insights into Turbulent Velocity Patterns and Energy Dissipation in Wall Flows

Rapid Summary

• The study, published in Proceedings of the National Academy of Sciences, Volume 122, Issue 17 (April 2025), examines the impact of smooth walls on turbulence structure.
• The research evaluates how the “law-of-the-wall” principle applies not only to mean velocity but also to turbulent fluctuations.
• Findings suggest that while this principle organizes empirical data effectively for mean velocity,its applicability may have limitations when addressing complex turbulent behaviors.
