چکیده
In the present work, radiation of sound waves from a coaxial duct is considered. This has an inner wall which infinite and piecewise acoustically absorbent material, while outer semi-infinite rigid. The analytical solution problem found by means Wiener-Hopf technique. Applying Fourier transformation to boundary value problem, explicit expression for scattered field obtained. end, some numerical results are displayed different parameters compared rigid case.

Casimir Energy of a Semi-Circular Infinite Cylinder
The Casimir energy of a semi-circular cylindrical shell is calculated by making use of the zeta function technique. This shell is obtained by crossing an infinite circular cylindrical shell by a plane passing through the symmetry axes of the cylinder and by considering only a half of this configuration. All the surfaces, including the cutting plane, are assumed to be perfectly conducting. The z...
متن کاملFlow around a rotating, semi-infinite cylinder in an axial stream.
This paper concerns steady, high-Reynolds-number flow around a semi-infinite, rotating cylinder placed in an axial stream and uses boundary-layer type of equations which apply even when the boundary-layer thickness is comparable to the cylinder radius, as indeed it is at large enough downstream distances. At large rotation rates, it is found that a wall jet appears over a certain range of downs...
متن کاملAcoustic Radiation from a Semi-infinite Annular Duct in a Uniform Subsonic Mean Flow
By using a Wiener-Hopf approach, an analytical description is derived of the scattered field of a harmonic sound wave coming out of an open ended annular duct (a semi-infinite cylinder inside of which, coaxially, is a doubly infinite hub), submerged in a subsonic, coaxial, uniform mean flow. The possibility of vortex shedding from the pipe exit edge is included. Explicit expressions are given f...
متن کاملHomogenization of convection-diffusion equation in infinite cylinder
The paper deals with a periodic homogenization problem for a non-stationary convection-diffusion equation stated in a thin infinite cylindrical domain with homogeneous Neumann boundary condition on the lateral boundary. It is shown that homogenization result holds in moving coordinates, and that the solution admits an asymptotic expansion which consists of the interior expansion being regular i...
متن کاملEdge-degenerate families of ΨDO’s on an infinite cylinder
We establish a parameter-dependent pseudo-differential calculus on an infinite cylinder, regarded as a manifold with conical exits to infinity. The parameters are involved in edge-degenerate form, and we formulate the operators in terms of operator-valued amplitude functions. Mathematics Subject Classification (2000).
