Amelioration de technique d'intensimetrie hydroacoustique

For industrial applications, a transfer matrix model can be used to study pressure and flow rate fluctuations propagation within ducts. If none analytical model exists, this matrix has to be identified according to acoustic intensity techniques.Pressure waves exert forces, which cause a compliant system to move, the motion causes pressure waves in return (fluid–structure interaction). An extension of acoustic intensity technique using several transducers is presented. To cite this article: J. Charley, C. R. Mecanique 331 (2003).
