Further development of a Dual-Probe Digital Sampling (DPDS) technique for measuring flow fields in rotating machines
furtherdevelopme00neuh.pdf (10.56Mb)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 generation1
' 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.
