Model Tests of Dynamic Action on the Atmospheric Boundary Layer – Linear Configuration of Ventilation Towers on a Rough Terrain

This paper describes model tests conducted at the Wind Engineering Laboratory of Cracow University of Technology as the first stage of studies on dynamic action on the atmospheric boundary layer in order to reduce the effects of air pollution and smog. It focuses on the cooperation between a series of ventilation towers placed one by one (or row by row) in order to generate a continuous airstream with sufficient velocity to aid the natural ventilation of urban areas. The tests were conducted for three different terrain categories with varying roughness. Also tested were different wind speeds, different spacing between the towers and different configurations of the towers in each row. As a preliminary set of tests, this enabled verification of the feasibility of the solution and its effectiveness on a rough terrain that simulates urban areas.
