Abstract:

In this two-volume monograph on the fundamentals of the generation of flow-induced sound and vibration, the subject area is developed from the essentials of fluid mechanics, vibration, and sound generation. This book provides a comprehensive and unified treatment of the mechanisms of flow-generated sound that occurs on ships and in marine machinery. Often the control of these mechanisms involves the essentials of both fluid mechanics and structural dynamics. Dynamical properties of various types of flow and of various structural elements that are typical of ship application are examined in detail beginning with the fundamentals of each physical source. Volume I provides for the treatment of elementary sources of flow noise and the principles of random vibration. Normal mode analysis is the cornerstone of the methods used to describe the behavior of flow induced vibration. Naval applications that involve turbulent boundary layer and lifting surface flows are discussed in Volume 2 ADA150673. Aerodynamic noise sources, in so far as they occur anogously in underwater acoustics, are examined in detail for low Mach number marine application.
