Acoustic wave propagation in a circular cosh duct carrying a mean flow
(Acoustical Society of America, 1987-09-01)
An analysis of acoustic wave propagation in a waveguide carrying an incompressible mean flow is presented. The radius of the waveguide is taken to vary slowly as a function of axial location. It is shown that the dynamic ...
Propagation of spinning acoustic modes in partially choked converging ducts
(Acoustical Society of America, 1982-04-01)
A computer model based on the wave-envelope technique is used to study the propagation of spinning acoustic modes in converging hard-walled and lined circular ducts carrying near sonic mean flows. The results show that ...
