Wave Radiation from Slender Bodies.
Abstract
Wave radiation by a slender body is discussed, with emphasis on the scale of the characteristic wavelength in relation to the disparate width and length of the body. The discussion is illustrated by reviewing the analysis of oscillatory forced motions of a slender floating body in otherwise calm water. Two complementary regimes are considered, where the wavelength is long (comparable to the body length) or short (comparable to the beam). The limitations of these two theories suggest the need for a unified approach, where geometric slenderness is assumed without restricting the wavelength. A possible approach to the unified theory is outlined in general terms, and illustrated in detail by considering the simpler physical problem of axisymmetric acoustic radiation by a slender body in an unbounded medium.
