Theory of Nonlinear Acoustics in Fluids. Book. © 2002. Download book PDF. Overview. Authors: Bengt O. Enflo, Claes M. Hedberg. Differs from mathematical books on nonlinear wave equations by its stress on their origin in physical principles and their use for physical applications.
1 sty 2002 · FUNDAMENTALS OF ACOUSTICS IN LIQUIDS The purpose of this chapter is to provide a general overview characterizing sound wave propagation in homogeneous liquids. A large body of existing literature describes various theories that relate the sound speed and attenuation of such liquids to rheological and thermodynamic parameters.
21 kwi 2022 · By coupling acoustic waves with fluids to generate acoustic radiation forces and acoustic streaming, acoustofluidic technologies offer a contact-free method for manipulating particles and...
1 sty 2004 · In this paper, weak formulations and finite element discretizations of the governing partial differential equations of three-dimensional nonlinear acoustics in absorbing fluids are presented.
25 paź 2024 · The physical principles and theoretical foundations of acoustics in fluids are first developed, including reflection and refraction of plane and spherical waves. The book then introduces notions of signal processing applied to sound waves, followed by radiation from surface or volume acoustic sources and the use of Green’s functions, as well ...
Howe presents useful background material on fluid mechanics and the elementary concepts of classical acoustics and structural vibrations. Using examples, many of which include complete worked solutions, he vividly illustrates the theoretical concepts involved.
