Measurement of two-dimensional periodical flow behind turbine guide-vanes by means of a split-fiber probe
Abstract
The accuracy of a split fiber hot-sensor anemometer in measuring nonstationary flow behind turbine guide vanes is discussed. The techniques used to calibrate split fiber probes are described, and experimental results are presented concerning the sources of error in flow measurements over a temperature range of 20 degrees. It is shown that the split fiber anemometer design compares favorably with hot-wire anemometers which require additional instrumentation for transforming the measuring value into an electrical signal.
