What is it about?
The modeling, prediction and control of turbulent flows through ducts and over surfaces require accurate information on the overlap region between the near wall turbulence and the outer parts of the flow. After nearly a century of utilizing "classical" relations to represent the overlap region in mean flow and in turbulence, new developments could bring a fresh "movement" in a field impacting many fields including energy saving, efficient transportation and future of environment.

Why is it important?
Achieving better modeling, prediction and control of omnipresent turbulence near surfaces which are integral part of many applications involving flow of fluids
Perspectives
This publication initiates a breakthrough to establish the domain and validity of application between two competing theoretical models, with one of them nearly a century old and one developed within last decade.
