  • The Radiated Field Generated by a Monopole Source in a Short, Rigid, Rectangular Duct
    Barbara Ann Lakota / National Aeronautics and Space Administr
    This thesis develops a method to model the acoustic field generated by a monopole source placed in a moving rectangular duct. The walls of the duct are assumed to be infinitesimally thin and the source is placed at the center of the duct. The total acoustic pressure is written in terms of the free-space pressure, or incident pressure, and the scattered pressure. The scattered p...
