Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

Modeling wall turbulence remains a major challenge, as a sufficient physical understanding
of these flows is still lacking. In an effort to move toward a physics-based model, AA …

Simulations and experiments at low Reynolds numbers have suggested that skin-friction
drag generated by turbulent fluid flow over a surface can be decreased by oscillatory motion …

In this work, a transformation, which maps the mean velocity profiles of compressible wall-
bounded turbulent flows to the incompressible law of the wall, is proposed. Unlike existing …

A direct numerical simulation of incompressible channel flow at a friction Reynolds number
($\mathit {Re} _ {{\it\tau}} $) of 5186 has been performed, and the flow exhibits a number of …

The quest for reductions in fuel consumption and CO 2 emissions in transport has been a
powerful driving force for scientific research into methods that might underpin drag-reducing …

Direct numerical simulations (DNS) are performed to investigate the spatial evolution of flat-
plate zero-pressure-gradient turbulent boundary layers over long streamwise domains () …

This article discusses the description of wall-bounded turbulence as a deterministic high-
dimensional dynamical system of interacting coherent structures, defined as eddies with …

This paper reviews the problems and successes of computing turbulent flow. Most of the flow
phenomena that are important to modern technology involve turbulence. The review is …

This article presents a review of historical and recent developments in the understanding of
equilibrium and non-equilibrium turbulent boundary layers at incompressible high-Reynolds …
