Caractérisation expérimentale du comportement hydroacoustique de turbomachines hydrauliques

Abstract

This paper deals with the methods useil in ortler to characterize a machine through a hydroacoustic tramfer matrix and source terms. Intensimetry techniques in rectilinear duets, which give these elements, are presented and discussed. These techniques use various plone waves propagation models which take into account the interactions between fluid flow and duet walL
