Application of energy conservation to the solution of radiation problems involving uniformly convected source distributions
Abstract
This paper describes a technique for determining the mean square asymptotic properties of the radiation fields of uniformly convecting multipole source distributions which avoids the usual asymptotic far field analysis of the integral representation of the wave field. The method is based on the principle of conservation of energy and is illustrated here by a consideration of the acoustic field radiated by convected sources located in free space and within a semiinfinite jet flow.
