Toward The Development of A Predictive Model of The Roughness Sublayer Flow Open
The non-linear interactions between large-scale momentum regions and small-scale structures induced by the presence of the roughness have been studied in boundary layers consisting of staggered cube arrays with plan area packing density of…

Assessment of inner–outer interactions in the urban boundary layer using a predictive model Open
Urban-type rough-wall boundary layers developing over staggered cube arrays with plan area packing density, $\unicode[STIX]{x1D706}_{p}$ , of 6.25 %, 25 % or 44.4 % have been studied at two Reynolds numbers within a wind tunnel using hot-w…

Structure of high Reynolds number boundary layers over cube canopies Open
The influence of a cube-based canopy on coherent structures of the flow was investigated in a high Reynolds number boundary layer (thickness $\unicode[STIX]{x1D6FF}\sim 30\,000$ wall units). Wind tunnel experiments were conducted consideri…

Spatial modulations of kinetic energy in the roughness sublayer Open
High-Reynolds-number experiments are conducted in the roughness sublayer of a turbulent boundary layer developing over a cubical canopy. Stereoscopic particle image velocimetry is performed in a wall-parallel plane to evidence a high degre…

Application of Laser Doppler Anemometry to estimate turbulent power spectra inside an urban canopy Open
In the present contribution, we propose to make use of Laser Doppler Anemometry to investigate the dynamics of the flow inside an urban canopy immersed into a thick turbulent boundary layer. Previous studies dedicated to such flows (Castro…
