Large Boundary Layer Wind Tunnel

The Large I.F.I. Boundary Layer Wind Tunnel has a test section cross section area of
2.7 m x 1.5 m. The wind speed above the boundary layer may be varied continuously up to a max. speed of  23 m/s. The atmospheric wind flow in the test section may be simulated  by using Counihan-turbulence generators and various surface roughness elements. The model scale of the wind flow is in the range of 1:150 through 1:500. Wind loads on buildings are determined according to the guidelines of the Wind Engineering Society (WTG) as recommended, e. g. in the German wind loading standard
DIN 1055-4:2005-03

A turntable of  2.5 m diameter is fitted in the test section. The measuring equipment includes a modern online pressure measuring system and a three-dimensional probe traversing mechanism.
