Hot-Wire Anemometry

Several hot-wire anemometer systems are available at the institute for the temporally high-resolution determination of the instantaneous values of velocity (3 components) and temperature. Using several probes, the formation of the temporal mean values of velocity and temperature as well as the auto- and cross-correlations of velocity and temperature fluctuations become available.
Hot-wire bridge systems:
  • 90N Streamline from Dantec, multi-channel system
  • 56C from Dantec, multi-channel system
  • IFA 300 from TSI, multi-channel system
  • 55M from Dantec, single-channel system, 8 units
Calibration unit:
  • a calibration unit is available for calibrating the speed and temperature probes
