Abstract:

Following a review of the technique, detailed descriptions are given of the procedures developed for calibrating and applying a system of two simple semi-conductor Kulite pressure probes to measure the velocity field from a high speed rotor. Calibration tests of a second generation probe set in a steady free jet, procedures for deriving calibration equations and subsequent verification tests are described in turn. Data reduction procedures and software involved in the application of the probe system with controlled digital data sampling to obtain the blade-to-blade velocity field in a machine are documented with examples of results. Successes and potential problems are evaluated. Author
