This book was released on 2010 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This master's-level thesis work had focused on the boundary treatments for computational fluid dynamics problems, especially those with unbounded domains. Therefore, it involved a rigorous literature survey on boundary treatment techniques. The primary interest in this effort was on one of the emerging concepts of boundary treatment for numerical schemes, namely the perfectly matched layer (PML) absorbing technique. PML equations were constructed in both Cartesian and generalized coordinate systems to widen its application in uniform and non-uniform grid structures. Throughout the study, Euler equations for perturbation equations linearized about a uniform mean flow were utilized, and flow that is parallel to an axis and flow that is at an arbitrary direction were considered. The PML formulation was validated and PML cases were simulated for a combination of absorbing coefficients and layer thickness in order to find the optimum performance of the technique. The results were analyzed, and the issues were documented. Furthermore, PML equations were constructed by splitting the velocity into three components. Discussion is provided on the need for a proper spacetime transformation, based on the literature study.

This book was released on 2008-02-27 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a survey of numerical methods for acoustics, namely the finite element method (FEM) and the boundary element method (BEM). It is the first book summarizing FEM and BEM (and optimization) for acoustics. The book shows that both methods can be effectively used for many other cases, FEM even for open domains and BEM for closed ones. Emphasis of the book is put on numerical aspects and on treatment of the exterior problem in acoustics, i.e. noise radiation.

Available in PDF, EPUB and Kindle. Book excerpt: These ten detailed and authoritative survey articles on numerical methods for direct and inverse wave propagation problems are written by leading experts. Researchers and practitioners in computational wave propagation, from postgraduate level onwards, will find the breadth and depth of coverage of recent developments a valuable resource. The articles describe a wide range of topics on the application and analysis of methods for time and frequency domain PDE and boundary integral formulations of wave propagation problems. Electromagnetic, seismic and acoustic equations are considered. Recent developments in methods and analysis ranging from finite differences to hp-adaptive finite elements, including high-accuracy and fast methods are described with extensive references.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents a state-of-art overview of numerical schemes efficiently solving the acoustic conservation equations (unknowns are acoustic pressure and particle velocity) and the acoustic wave equation (pressure of acoustic potential formulation). Thereby, the different equations model both vibrational- and flow-induced sound generation and its propagation. Latest numerical schemes as higher order finite elements, non-conforming grid techniques, discontinuous Galerkin approaches and boundary element methods are discussed. Main applications will be towards aerospace, rail and automotive industry as well as medical engineering. The team of authors are able to address these topics from the engineering as well as numerical points of view.

Download or read book Computational Aeroacoustics written by Christopher K. W. Tam and published by Cambridge University Press. This book was released on 2012-09-28 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational aeroacoustics (CAA) is a relatively new research area. CAA algorithms have developed rapidly and the methods have been applied in many areas of aeroacoustics. The objective of CAA is not simply to develop computational methods but also to use these methods to solve practical aeroacoustics problems and to perform numerical simulation of aeroacoustic phenomena. By analysing the simulation data, an investigator can determine noise generation mechanisms and sound propagation processes. This is both a textbook for graduate students and a reference for researchers in CAA and as such is self-contained. No prior knowledge of numerical methods for solving partial differential equations (PDEs) is needed, however, a general understanding of partial differential equations and basic numerical analysis is assumed. Exercises are included and are designed to be an integral part of the chapter content. In addition, sample computer programs are included to illustrate the implementation of the numerical algorithms.

This book was released on 2014-08-05 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews a variety of methods for wave-based acoustic simulation and recent applications to architectural and environmental acoustic problems. Following an introduction providing an overview of computational simulation of sound environment, the book is in two parts: four chapters on methods and four chapters on applications. 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.
