Caractérisation expérimentale du comportement hydroacoustique de turbomachines hydrauliques
Experimental characterization of the hydroacoustic behavior of hydraulic turbomachines
Laboratoire de Mécanique de Lille, DRA CNRS 1441, ENSAM
This paper deals with the methods used in order to characterize a machine through a hydroacoustic transfer matrix and source terms. Intensimetry techniques in rectilinear ducts, which give these elements, are presented and discussed. These techniques use various plane waves propagation models which take into account the interactions between fluid flow and duct wall.
