The use of wind tunnels is a vital part of the field of fluid mechanics. This project
have aimed to construct a small wind tunnel intended to be used in a laboration
for an introduction course in the field of fluid mechanics at Chalmers University of
Technology. The laboration aims to demonstrate stall of a wing and measure the
resulting forces on the wing depending on its angle of attack. The airflow in the
tunnel was set to reach speeds around 10 m/s, and be parallel, with low turbulence
intensity. Through the use of design ideas and rules of thumb produced by previous
studies, the project resulted in a wind tunnel that is small enough to be fitted upon
a normal sized table. Testing showed that the resulting airflow in the tunnel could
reach speeds up to 12 m/s, and that the flow was parallel, except for some small
variations.
