Hydrodynamics and sound

Detailed Summary of the Book

"Hydrodynamics and Sound" begins by laying out the core mathematical tools and frameworks essential for understanding fluid motion and acoustics. Topics such as the Navier-Stokes equations, potential flow theory, and boundary layer dynamics are discussed in detail. These foundational concepts provide the basis for examining how fluids generate and modify sound waves.

The text progresses into advanced topics, such as the mechanics of sound emission from turbulent flows, vortex-induced vibrations, and the interactions of acoustic waves with solid boundaries. Special emphasis is placed on the contributions of small-scale fluid motions to large-scale acoustic phenomena, enabling readers to grasp the multiscale dynamics involved in hydrodynamic systems.

Later chapters delve into the study of aeroacoustics, including the generation of aerodynamic sound due to unsteady flows around structures. The book integrates theoretical insights with practical applications by addressing noise reduction techniques in industries such as aerospace and marine engineering. Each chapter is supported by detailed derivations, carefully explained assumptions, and illustrative examples to enhance understanding.
