Investigation of a non-homogeneous penetrable roughness in wind tunnel (English)
0 references
The air flow within and above a 120 mm high canopy located on a wind tunnel ground has been investigated using thermal anemometry. The canopy consists of an array of ``trees'' constructed with flat-plate triangular, 70 mm high ``crowns'' at the top of cylindrical ``stems'', allowing several orientations to the air flow. Mean velocity and turbulence intensity distributions, together with turbulence spectra and their transformation along the canopy, are discussed.
