Wind tunnel is an important tool for wind for wind -related researches, such as studying the wind -induced response of man-made structures, which are submerged in the ABL. Different terrain conditions would have the different influence on the studied object, so a proper simulation for the ABL using passive simulation devices, spire and roughness element, is essential. The objectives of this study include the design and the manufacture of the spires and roughness elements, studying the effect of the spire and roughness element on the simulated flow characterics of the generated the ABL. And the atmospheric boundary layers of terrain type "A" and "B" have been simulated in an open-loop wind tunnel using spires combined with roughness. |
