| Abstract | |
The structure of the wind field and atmospheric turbulence generated inside a shallow cavity is analyzed using wind tunnel tests and a 2-D Large-Eddy Simulation (LES) model. The cavities are static mock-up that can represent small clearings inside forest in Amazonia or urban canyons representing the geometry of modern cities. The results suggest that, despite differences in the scales, the organization of turbulence in the two experiments contains similarities in some regions. It was verified the dependency of the turbulence, wind profile and Turbulent Kinetic Energy dependence against flow above canopy, its size and its relative position inside the gap. (AU) | |
