The Design of an Open-Jet Wind Tunnel for Model Testing 2002-01-3340

A 2m2 wind tunnel has been constructed at Durham University. An open jet, open return design with sub-atmospheric working section and two double-entry centrifugal fans was selected.
The tunnel was designed using a combination of empirical data, theoretical calculations, and CFD simulations.
Overhead model support is provided by a high-stiffness structure which is independent of the main tunnel. The model pitch and ride height is computer controlled and monitored.
Extensive instrumentation has been developed with an emphasis upon unsteady measurement. This includes time-accurate measurement of pressures on the model and in the wake and time-accurate measurement of velocities either using probes or PIV.
