## Abstract

In this report a wind tunnel is described in term of its design, its construction as well as in its validation of flow features. This wind tunnel is characterized by a new unconventional design. The innovative design allows an unusual long flow test section (in particular important for turbulence research) relative to the total size of the wind tunnel. Thus, the new design enables a much better use of space in comparison to a wind tunnel with conventional design. The design is characterized by two strong expansions of flow, namely a wide angle diffusor and strong expanding corner. Among other things, investigations about these flow expanding components enlarge the existing knowledge and show new possibilities.
