Urban street canyon flows play a central role in microclimate control, from street canyon to
neighbourhood and city scale, which affect pollutant dispersion, thermal comfort of residents …

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

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 …

We perform direct numerical simulations (DNS) of a turbulent channel flow over porous
walls. In the fluid region the flow is governed by the incompressible Navier–Stokes (NS) …

Interfacial boundary conditions determined from empirical or ad hoc models remain the
standard approach to model fluid flows over porous media, even in situations where the …

The axisymmetric creeping flow of micropolar fluid past a porous surface saturated with
micropolar fluid is investigated analytically. A sphere's surface is assumed to have adequate …

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 …

The modal and non-modal linear stability analyses of a three-dimensional plane Couette–
Poiseuille flow through a porous channel are studied based on the two-domain approach …

We develop asymptotic modeling for two-or three-dimensional viscous fluid flow and
convective transfer at the interface between a fluid and a porous layer. The asymptotic …

For the numerical investigation of transpiration cooling problems, often two-domain models
are used. Different systems of governing equations are solved in a hot gas and a porous …
