Unsteady Effects on the Measurement of Total Pressure in Rotating Machines.
Abstract
The pressure averaging of different pneumatic impact probes was investigated using a periodic flow generator in order to establish corrections for probe measurements made in a compressor, and to guide in the selection of probe geometries to be used in the compressor. The Kulite transducer probe used as a reference in these measurements was also used, with both continuous and synchronized sampling, to measure the flow from the compressor rotor. It was concluded that the corrections required to be made to the pneumatic impact pressure measurements were negligible at 50% design speed, but might be significant at higher speeds if the probe system volume were not properly sized.
