    • Acoustic wave propagation in a circular cosh duct carrying a mean flow 

      Thompson, Charles; Sen, Rahul (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 ...
    • Scattering of acoustic waves in a waveguide 

      Sen, Rahul; Thompson, Charles (Acoustical Society of America, 1987)
      The problem of scattering from boundary discontinuity in a waveguide is discussed. The relationship between the static and dynamic representations of the scattered pressure field will be investigated for those frequencies ...
