City St George's Low Turbulence Wind Tunnel
City, University of LondonLondon
NWTF lists City St George's Low Turbulence Wind Tunnel as an active low-speed, closed-return facility in London. Its current facility page says the tunnel is used for laminar-to-turbulent transition and two- and three-dimensional boundary-layer studies, and lists a 0.91 m × 0.91 m × 3 m test section.

Key facts
- Published research use
- NWTF says the tunnel is exclusively used for laminar-to-turbulent transition studies because of its very low turbulence intensity, and that both two- and three-dimensional boundary-layer studies are carried out there.
- Published facility status
- The NWTF facility page lists the tunnel as active, low speed and closed return, with City University London at Northampton Square, London, EC1V 0HB as owner.
Testing capabilities
Transition and boundary-layer studies
NWTF says the tunnel is used for laminar-to-turbulent transition studies and for both two- and three-dimensional boundary-layer studies. Its page also says commercial contract projects use the facility, including collaborations with Airbus and Bombardier among others.
Flow measurement and visualisation
The facility page lists 64-channel simultaneous data acquisition for pressure and velocity outputs, hot-wire anemometry, and flow visualisation by video, tuft and surface fluorescent oilflow.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Test section and maximum flow speed | 0.91 m × 0.91 m × 3 m test section; 45 m/s maximum flow speed | These are published facility figures. Confirm the usable model envelope, blockage, support arrangement and applicable flow conditions for a particular programme. |
| Published turbulence intensity | < 0.01% up to 20 m/s | The facility page states this turbulence-intensity figure for speeds up to 20 m/s. It should not be extrapolated to every speed, model or measurement arrangement. |
Access and contact
The NWTF facility page links to a Get in contact route. NWTF's contact page says users interested in its facilities can submit a Facilities enquiry and asks for requested wind-speed range, maximum model dimensions, measurements, testing days and preferred timing. Confirm the tunnel's current availability, technical suitability and any acceptance conditions with NWTF.
