ABSTRACT

A vorticity, caused by a flow passing through the architectural or the forest irregularities of a ground relief, is studied. Physical description of peculiarities of such flow is given in terms of the model of a penetrable roughness (PR). The experimental setup and obtained results are discussed. Measurements were made for the smooth boundary, the boundary with the single obstacle, and the PR-boundary. Comparison of the data allowed to distinguish the parameters characterizing the, so called, canopy vorticity.
