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 …

Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

A new direct numerical simulation of a Poiseuille channel flow has been conducted for a
friction Reynolds number of 10 000, using the pseudospectral code LISO. The mean …

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 …

Large-eddy simulation (LES) has proven to be a computationally tractable approach to
simulate unsteady turbulent flows. However, prohibitive resolution requirements induced by …

While data-based approaches were found to be useful for subgrid scale (SGS) modeling in
Reynolds-averaged Navier-Stokes (RANS) simulations, there have not been many attempts …

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 …

Similar to other renewable energy sources, wind energy is characterized by a low power
density. Hence, for wind energy to make considerable contributions to the world's overall …

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

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