An analytical study of radiation from finite cylindrical shell with infinite rigid extensions is presented. The shell is immersed in an infinite surrounding fluid at rest and contains flowing fluid. The shell is excited either by an harmonic driving force or by internal acoustic sources. The method of resolution consists in expanding the shell wall displacements in series of the simply supported shell eigen modes.
