Calibration of surface mounted hot films
Calibration of Surface Mounted Hot Films Probes

  • Surface mounted hot-film sensors attached to a low pressure Turbine blade.

  • Multi-Channel anemometer used

  • Periodic unsteady inlet flow condition.

  • Anemometer: Samples were taken at a rate of 10 kHz for each of the 50 revolutions of the wake generator.

  • The data were ensemble-averaged with respect to the rotational period of the wake generator.

Connection pins to anemometer-switch board
