Following the idea of multiple scales, new “slow” spacial scales are introduced, which are defined as the usual physical spacial scale multiplied b

It is easy to show that the computed acoustic wave solutions are good approximations of those of the exact solutions of the linearized Euler equations as long as the wavenumbers are in the long wave range. Computed waves with higher wavenumber, or the short waves, generally have totally diff

That work has more or less dominated the subsequent development of this field, which has received renewed attention over the past few years as a result of recent efforts to develop an updated high speed transport — whose successes will largely depend on whether its jet exhaust noise can be r

The simple class of problems considered in the present paper involves the radiation of sound by vortex flows. The interesting feature of these flows is that the loss of angular momentu
