Certain surfaces that exhibit small textured features can interact with near-wall turbulence
and reduce drag, which is of great interest to industries in the aerospace, naval, transport …

Natural and engineered surfaces are never smooth, but irregular, rough at different scales,
compliant, possibly porous, liquid impregnated or superhydrophobic. The correct numerical …

We explore the ability of anisotropic permeable substrates to reduce turbulent skin friction,
studying the influence that these substrates have on the overlying turbulence. For this, we …

The phenomenon of the Stokes–Darcy flow in coupled systems comprising a clear channel
and a complex 3D porous medium is investigated through both numerical and theoretical …

This paper presents image velocimetry measurements on turbulent flows adjacent to a
permeable bed made of randomly packed glass particles. For measuring flow velocities …

The surface texture of materials plays a critical role in wettability, turbulence and transport
phenomena. In order to design surfaces for these applications, it is desirable to characterise …

A new numerical continuum one-domain approach (ODA) solver is presented for the
simulation of the transfer processes between a free fluid and a porous medium. The solver is …

Coupled free-flow and porous-medium systems appear in a variety of industrial and
environmental applications. Fluid flow in the free-flow domain is typically described by the …

Subsurface structures generally exhibit strong heterogeneities at multiple spatial scales. In
this study, two-and three-scale high-order models are developed to effectively predict …
