The Aarhus Wind Tunnel Simulator II (AWSTS II) consists of an approximately 40 m3 environmental chamber housing a recirculating wind tunnel. It is used for studying a wide variety of research topics including dust resuspension, sand transport, Carbon Dioxide ice formation, volcanic ash behaviour etc. Also, characterisation and accelerated stress testing of instrumentation for Mars missions or high altitude terrestrial applications are being carried out.
Key physical parameters can be recreated such as:
This facility utilizes a network based control and data logging system, where all important parameters are continuously recorded.
It employs a sophisticated 2 dimensional Laser Doppler Velocimeter for the quantifying and studying aerosol particles and flow.
For characterising boundary layers and measuring wind speeds when no particles can be used for seeding, we use an array of Pitot tubes with extraordinary high resolution.
