摘要：

A method is developed for the prediction of noise from rotors in an axisymmetric duct at rest. The technique combines a previously developed model for noise from disc sources with a boundary integral equation method for scattering from the duct surface. Recent developments in the theory of Gaussian quadrature and generalized elliptic integrals are used to simplify the implementation of the formulation. The sound field of a simplified model ducted rotor is then calculated and its structure examined in the framework of known features of the field around rotating sources. It is found that, as for an open rotor, the sonic radius plays an important role in the structure of the field. (C) 2002 Elsevier Science Ltd. All rights reserved.
