BMT operates a number of major wind tunnel facilities including a large Boundary Layer Wind Tunnel and a High-Speed Uniform Flow Wind Tunnel.
Boundary Layer Wind Tunnel
Closed return type with a glass walled working section, and atmospheric boundary layer simulation, used for a wide range of applications including wind loading, safety, risk and environment impact for offshore installations.
Specifications and Key Features
- Test section - 4.8m x 2.4m x 15m
- Wind speed range - 0.2 to 45m/s
- Full atmospheric boundary layer simulation
- 4.4m diameter motorised multiple plate turntable
- 3-dimensional computer controlled traverse system
High-Speed Uniform Wind Tunnel
Closed return type, with a glass walled working section, used for section model tests and applications requiring low turbulence flow or uniform turbulent flow.
Specifications and Key Features
- Octagonal test section 2.7m x 2.1m
- Wind speed range 0.2 - 65m/s
- Turbulence grids
- Motorised turntable
- Dynamic rig for aero-elastic response simulations
Instrumentation
The wind tunnels are equipped with comprehensive data acquisition and instrumentation, which include:
- Sensitive 6-component high frequency force transducer
- A wide range of 3-component and 6-component static force transducers
- Electronic multiple Channel low-range pressure scanning system (>500 channels)
- Multi-channel hot-wire and hot film anemometry for wind speed and turbulence measurements
- Irwin probes for fluctuating wind speed tests
- Multi-channel non-contacting displacement transducer system
- Accelerometers for flow-induced vibration measurements
- Flow visualisation facilities including smoke generation
- Analogue & digital video recording with editing facilities
