Abstract The Elliptic Blending Reynolds Stress Model (EB-RSM), originally proposed by
Manceau and Hanjalić (2002) to extend standard, weakly inhomogeneous Reynolds stress …

We carry out direct numerical simulations of flow in a plane open channel at friction
Reynolds number up to, in line with observations made in shear-free Couette–Poiseuille …

Turbulence in open channel flows is ubiquitous to hydro-environmental applications and
has recently increased in importance with the deployment of tidal stream turbines, as …

We measure solute transport near a turbulent air–water interface at which there is zero
mean shear. The interface is stirred by high-Reynolds-number homogeneous isotropic …

We report on direct numerical simulations to examine the spectral behaviour of turbulence
close to and at a flat, stress-free surface. We find, consistent with field measurements near …

Direct numerical simulation is performed to study the effect of progressive gravity waves on
turbulence underneath. The Navier–Stokes equations subject to fully nonlinear kinematic …

Due to its multiscale and multi-layer natures, the coherent structures of turbulent in the open
channel flow is complex and difficult to be visualized for understanding its evolution. In this …

Free-slip boundary conditions are routinely used in simulations of bluff body wakes without
spanwise homogeneity. The impact of the free-slip condition on the wake behind a curved …

The physics involved in the interaction between statistically steady, shearless turbulence
and a blocking surface is investigated with the aid of direct numerical simulation. The …
