This paper deals with linear acoustic waves propagating in parallel shear flows of an inviscid ideal gas in a two-dimensional duct. General properties of the dispersion relation (eigenvalue relation) for the neutralIy stable acoustic modes are derived. Asymptotic behaviours of the eigensolutions for
This paper describes the development of robust procedures yielding reliable estimates of the nett sound power #ux associated with one-dimensional wave motion under strongly reactive conditions in #ow ducts. In such reverberant situations, the measurements must be su$ciently precise to clearly identi
