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 …

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 …

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 …

Closed-loop turbulence control is a critical enabler of aerodynamic drag reduction, lift
increase, mixing enhancement, and noise reduction. Current and future applications have …

Considerable discussion over the past few years has been devoted to the question of
whether the logarithmic region in wall turbulence is indeed universal. Here, we analyse …

The effect of domain size on direct numerical simulations of turbulent channels with periodic
boundary conditions is studied. New simulations are presented up to Re τ= 4179 in boxes …

One-point statistics are presented for new direct simulations of the zero-pressure-gradient
turbulent boundary layer in the range Re θ= 2780–6680, matching channels and pipes at …

Taylor-Couette flow, the flow between two coaxial co-or counter-rotating cylinders, is one of
the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters …
