The facilities are exceptional in providing both Eulerian and Lagrangian measurements with the highest technologically realizable speed and resolution. They are versatile and flexible in the installation of other flow generators and instruments.
- Highest turbulence levels under well-controlled conditions
- Flow resolvable over all scales by current measurement technology;
- High-pressure compatible measurement systems: 3D LPT, Tomo PIV, LDV, PDPA, hot-wire.
The facilities are housed in a newly constructed experimental hall that is vibration isolated and temperature stabilized. Safety control systems are installed to support daily use of pressurized gases and high-power lasers. High bandwidth fibre optics links the facilities to a 288-processor data analysis cluster. A 36m2 class 1000 clean room is available for micro fabrication of sensors. The institute installed a gas liquefaction system in a separate building, where 13 tons of SF6 gas are stored. The operational pressure of the system ranges from 1mbar to 19bar.
The facilities include the following equipment: a 3D Lagrangian particle tracking system consisting of 4 phantom V7b cameras (800x600 at 6k fps and 256x256 at 36k fps), a Tomo-PIV system (LaVison) with 4 Phantom cameras (2000x2000 at 500fps), a 3 component LDV system (TSI) with a PDPA for particle sizing, a Dantec hot-wire system, nano-fabricated hot-wires (Princeton). All of the above equipment is compatible with high pressure up to 15 bar. In addition, 2 frequency doubled, high-repetition-rate and high-power Nd:YAG lasers (100kHz and 50W), 2x5W argon-ion lasers, 2 linear optical rails (7m, 9m) with linear motors (capable of driving 350kg at speeds up to 5m/s), optics, data analysis software, and a computing and storage cluster are available.
