Available in PDF, EPUB and Kindle. Book excerpt: Senior level/graduate level text/reference presenting state-of-the- art numerical techniques to solve the wave equation in heterogeneous fluid-solid media. Numerical models have become standard research tools in acoustic laboratories, and thus computational acoustics is becoming an increasingly important branch of ocean acoustic science. The first edition of this successful book, written by the recognized leaders of the field, was the first to present a comprehensive and modern introduction to computational ocean acoustics accessible to students. This revision, with 100 additional pages, completely updates the material in the first edition and includes new models based on current research. It includes problems and solutions in every chapter, making the book more useful in teaching (the first edition had a separate solutions manual). The book is intended for graduate and advanced undergraduate students of acoustics, geology and geophysics, applied mathematics, ocean engineering or as a reference in computational methods courses, as well as professionals in these fields, particularly those working in government (especially Navy) and industry labs engaged in the development or use of propagating models.

The first part explains the fundamentals and advanced techniques for three popular methods, namely, the finite-difference time-domain method, the finite element method, and the boundary element method, as well as alternative time-domain methods. The second part demonstrates various applications to room acoustics simulation, noise propagation simulation, acoustic property simulation for building components, and auralization. This book is a valuable reference that covers the state of the art in computational simulation for architectural and environmental acoustics.
Download or read book Research in Computational Methods for Structural Acoustics written by and published by . This book was released on 1996 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of structural acoustics and fluid-structure interaction involves the solution of problems of acoustic radiation and scattering, elastic and structural wave propagation, and their interaction. Only relatively few, simple cases can be solved analytically and when the wavelength is of the same order as characteristic length scales asymptotic methods usually cannot be employed. Thus, most configurations of practical interest must be solved by standard computational tools such as boundary element, finite difference and finite element methods. Exterior problems of wave propagation pose a unique challenge to computation since the unbounded region is inappropriate for direct implementation of computational techniques. The derivation of mathematically sound continuous formulations that provide suitable bases for the computation of solutions to exterior problems of acoustics is not a trivial task. The performance of numerical methods that are then based on such a formulation, in terms of accuracy and convergence, as well as computational cost effectiveness, also requires careful consideration. This work reviews recent developments in numerical methods that address these issues.

Download or read book Computational Methods for a Class of Problems in Acoustic Elastic and Water Waves written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is concerned with numerical solutions of a class of boundary value problems in acoustic, elastic and nonlinear water waves, and consists of two independent parts. In the first part, we deal with the application of variational methods, including the finite element method, the boundary element method as well as their coupling, to solutions of three specific two-dimensional boundary value problems in acoustics and elastodynamics. To be more precise, we first study the application of finite element methods to the solution of exterior Neumann problems in acoustics. The original problem is reduced to a nonlocal boundary value problem in a bounded domain by introducing an artificial boundary. We employ, respectively, a direct boundary integral equation method and a Foureier series expansion method to define corresponding Dirichlet-to-Neumann mappings on the artificial boundary. Weak formulations for the resulting nonlocal boundary value problems are carefully studied. Thereafter, we employ the boundary element methods to seek solutions of two type of transmission problems in acoustics and fluid-structure interaction, respectively. The original transmission problems are reduced to a system of coupled boundary integral equations. We are interested in their weak formulations. Uniqueness and existence for the weak solutions are carefully investigated in appropriate Sobolev spaces. For each specific problem, a sequence of numerical tests are implemented to illustrate the accuracy and efficiency of the solution procedures. During these tests, in addition to the standard boundary element method, fast multipole methods are also employed for the numerical treatment of boundary integral equations to be involved. In the second part, we present an accurate and efficient numerical model for the simulation of fully nonlinear, three-dimensional surface water waves on infinite or finite depth. The numerical method is based on the reduction of the problem to a lower-dimensional Hamiltonian system involving surface quantities alone. This is accomplished by introducing an Dirichlet-to-Neumann mapping which is represented in terms of its Taylor series expansion in homogeneous powers of the surface elevation. The validity of the model and the efficiency of the method are illustrated by simulating the long-time evolution of two-dimensional steadily progressing waves, as well as the development of three-dimensional (short-crested) nonlinear waves, both in deep and shallow water.

In fact, with the development and improvement of innovative computational techniques and with the growing need for predictive models, an impressive boost has been observed in several research and application areas, such as noise control, indoor acoustics, and industrial applications. This led us to the proposal of a special issue about “Modelling, Simulation and Data Analysis in Acoustical Problems”, as we believe in the importance of these topics in modern acoustics’ studies. In total, 81 papers were submitted and 33 of them were published, with an acceptance rate of 37.5%. According to the number of papers submitted, it can be affirmed that this is a trending topic in the scientific and academic community and this special issue will try to provide a future reference for the research that will be developed in coming years.
