A development of generalized differentiation with respect to time is given within the structure of the functional approach to generalized function theory. The analysis is in parallel with techniques used in an earlier publication by F. Farassat and t

A two-step method for evolving two-dimensional nonlinear acoustic systems with flow to a periodic steady state is presented. In the first step of the method, the full nonlinear system governing acoustic disturbances is integrated numerically starting

Application of the Kirchhoff formula for subsonically moving surfaces to scattering of sound from a moving rigid body is described. The formulation leads to a singular integral equation that yields surface values of the field. The integral equation i

The acoustic scattering of an incident wave by a rigid body can be described by a singular Fredholm integral equation of the second kind. This equation is derived by solving the wave equation using generalized function theory, Green's function for th

An exact equation governing the transport of energy associated with disturbances in an arbitrary steady flow is derived. The result is a generalization of the familiar concept of acoustic energy and is suggested by a perturbation expansion of the gen

In this paper we discuss two problems of classical duct acoustics: (1) wave propagation in infinite ducts with uniform flow based on a graphical approach, and (2) detection of mode radiation from a duct by an external circular microphone array. In (1
