Abstract: We discuss how to prescribe a wave packet in a round cylindric channel as an initial data. We consider non-zero azimuthal or radial wave numbers. Parameters of the wave packet are chosen for convenience in numerical simulaition. Explicit expressions for initial data and pressure spectrum are presented.
Keywords: channel with flow, sound field, initial conditions, spectrum.
