Introduction of Boundary -layer Wind Tunnels

We have installed two wind tunnels of closed return type for carrying out our research in wind environment around tall buildings, aerodynamic stability of structures, and design of external materials.One of these tunnels has a working section of 1.8m in height, 2.0m in width and 16m in length.The other has a working section of 2.0m in height, 3.0m in width and 16m in length.The characteristics and performance of the wind tunnels are presented in this paper.
