  8. Calibration of Surface Mounted Hot Films • 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 Blade fixture to test section Hot film probe embedded in a foil, see next slide TPFL: The Turbomachinery Performance and Flow Research Laboratory Texas A&M University M.
