Tomographisches Messverfahren fuer die Gasverteilung in einer Axialpumpe bei Zweiphasenbetrieb Aktueller Abschlussbericht zum Vorhaben 7531.50-03-0370-99/3. Berichtszeitraum: 01.07.1999 - 31.12.2000

Abstract

A new method is described for measuring the local phase distribution in rotating pump rotors or similar objects by gamma tomography. Tomographic projections are made in intervals of only about 100 #mu#s. At a relevant speed of about 25 s"1, this means a comparatively high angular resolution of 0.9 , which provides more detailed information on gas distribution. The transport processes in the rotor of an axial pump during pumping of an air/water mixture were visualized by the tomograph. The effects of changes in the external flow parameters and of variations of the working point on the spatial phase distribution inside the rotor were shown.
