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
The propagation of small disturbances in an annular duct with a mean vortical swirling flow is studied. The disturbance velocity is split into a nearly-convected part and a nearly-sonic part, obeying weakly coupled equations. A normal mode analysis shows that the eigenvalues are segregated into a fi
