Atmospheric boundary layer simulation in a short wind tunnel
Shojaee, S. M. N.; Uzol, O. & Kurç, Ö.
Abstract
This paper presents the design, computational
analysis and experimental study of passive device configurations
which utilized in the Ankara Wind Tunnel to
simulate the atmospheric boundary layer within the test
section. The study here is part of a joint project between the
Aerospace and Civil Engineering Departments at Middle
East Technical University, which involves testing of highrise
building models in the Ankara Wind Tunnel. The
design consists of spires and rows of cubical surface
roughness elements at the inlet. The preliminary computational
analysis shows that the current design may provide
the desired boundary layer thickness at about 4.0 m
downstream of the test section inlet, which leaves enough
room for the building models to be placed in the test section.
This study also helps obtaining a preliminary understanding
of the boundary layer development and reducing
the tunnel operation time and cost during the actual
experimentation phase. At the end, experimental results
show acceptable results of this study.
