Pagination or Media Count:
This fast-response total pressure probe is intended for use in the study of unsteady flows in turbomachines. Emphasis is on the design and calibration of this probe, which uses a temperature-compensated transducer to obtain both the AC and DC components of the fluctuations. A description of the calibration procedure and calibration device, a Galton Whistle, employed to determine the time-dependent response of this probe is presented. In addition, typical data demonstrating the use of this probe in an axial flow fan are discussed.
