| The air flow within and above a 120 mm high canopy located on a wind tunnel ground plane 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. It is intended that the results should be applicable to several fluid mechanics disciplines by means of a general concept of Penetrable Roughness. |
