Small Boundary-Layer Wind Tunnel

The institute has designed and constructed a 1:3 scale Small Boundary-Layer Wind Tunnel (Kleiner Grenzschichtwindkanal, KGWK) for student work. The KGWK can also be equipped with different inlet obstacles and ground roughness to generate different velocity profiles and turbulence structures.

The institute has designed and constructed a 1:3 reduced boundary-layer wind tunnel (Kleiner Grenzschichtwindkanal, KGWK) for student work.

Like its big brother, the KGWK is of Eiffel type and has a rectangular cross section.
The KGWK can also be equipped with different inlet obstacles and ground roughness to create different velocity profiles and turbulence structures.

At the moment, the KGWK is examining the same landscape model of the Albaufstieg near Schnittlingen (Donzdorf, district of Göppingen) as the GWK, but on a scale of 1:1200.

Due to the smaller dimensions of the channel, the bottom boundary layer of the KGWK can be measured within a short time with the help of a specially manufactured, so-called Pitot calculator (see picture).
