TL;DR: In this article, a consistent theory of self-similarity and of equilibrium in the outer region of turbulent boundary layers was presented, where the outer scales are left unspecified and it is not assumed that the mean velocity defect and the Reynolds stresses share a common velocity scale.

TL;DR: In this paper, the authors compared the performance of large-defect adverse-pressure gradient turbulent boundary layers using six experimental and numerical databases including a new direct numerical simulation of a strongly decelerated non-equilibrium turbulent boundary layer.

TL;DR: In this article, the characteristics of coherent structures in a strongly decelerated large-velocity-defect boundary layer are analyzed by direct numerical simulation, where the boundary layer starts as a zero-pressure-gradient boundary layer, decelerates under a strong adverse pressure gradient, and separates near the end of the domain in the form of a very thin separation bubble.

TL;DR: In this article, a new method for characterizing cross-sections of vortices in turbulent flows is described. But the method is not robust, robust, not selective, and above all, much less contaminated by shear than the existing methods.

TL;DR: In this article, a clear and consistent framework for the analysis of the outer region of adverse-pressure-gradient turbulent boundary layers is established based on basic principles and theory, and the help of six adverse pressure gradient turbulent boundary layer databases and a zero pressure gradient one.
