Chalmers wind tunnel is a so called closed circuit tunnel with test section dimensions 3,00X1,80X1,25 m3 and a speed range of 0-60 m/s.
The tunnel is used in both undergraduate and research activities. It is equipped with balances for force measurements on immersed bodies, as well as detailed flow field studies using hot wire anemometry, optical measurement techniques and advanced pressure measurements. In 2008 Chalmers Aerodynamic Wind Tunnel re-entered the Subsonic Aerodynamic Testing Association (SATA).
Presently the tunnel is being used both for basic and applies research. Fundamental research includes transition studies, boundary layer investigations and wake flows. The applied research is focused on road vehicle aerodynamics where decreased aerodynamic drag is the main focus in order to reduce the fuel consumption and consequently CO2-emissions.
The Road Vehicle Aerodynamics research group with five on going research projects performs a number of experimental studies within these laboratory facilities.
