City St George's Transonic/Supersonic Wind Tunnel
City St George's, University of LondonLondon
NWTF identifies the Transonic Wind Tunnel at City St George's, University of London as an active, closed-return, induction-driven facility. Its current page lists a 0.2 m × 0.25 m × 0.5 m test section, Mach 0.5 to 2.0 range and aerospace-related studies including shock-wave/boundary-layer interaction and turbine-blade aerodynamics.

Testing capabilities
Aerospace-related flow studies
NWTF says the transonic facility is used mainly for aerospace-related studies and lists shock-wave/boundary-layer interaction, turbine-blade aerodynamics, rocket science and the effect of heat exchange as examples of studies.
Optical and flow measurement methods
The page lists pressure, surface-shear, Schlieren and shadowgraph techniques, PIV and 3D LDV. It also says the tunnel has a full optical-access section for techniques including Laser Doppler Anemometry, stereoscopic particle-image velocimetry and flow visualisation.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Published test section and Mach range | 0.2 m × 0.25 m × 0.5 m test section; Mach 0.5 to 2.0 | These are published facility figures. Confirm the usable model envelope, blockage, support arrangement, total-pressure condition and applicable run conditions for a particular programme. |
| Published run condition | Up to 30 s run time; total pressure 1 to 1.2 bar | The facility page presents these as performance figures. They do not establish a guaranteed combined operating envelope for every model, measurement arrangement or test condition. |
