Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates a new method for predicting the farfield scattered pressure of a plane wave due to an infinite cylinder of noncircular cross section. Both impenetrable and penetrable :fluid boundary condi tions will be treated for several types of cross sections and for a large frequency range. This new method requires the conformal mapping of both the exterior and interior of a closed surface to a semi-infinite strip. Numerically efficient algorithms wi ll be presented for both of these cases. A new method for satisfying the boundary conditions will be developed, as well as an efficient algorithm for generating the required modal functions on the boundary. Numerical results are presented for cross sections in the shape of an ellipse, square, and three leaf clover. In all cases, the results compare extremely well with exact or high frequency asymptotic results.

Download or read book Sound Scattering on Spherical Objects written by Tom Rother and published by Springer Nature. This book was released on 2020-02-13 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to scattering from a practical/numerical point of view. The focus is on basic aspects like single scattering, multiple scattering, and whether inhomogeneous boundary conditions or inhomogeneous scatterers have to be taken into account. The powerful T-matrix approach is explained in detail and used throughout the book, and iterative solution methods are discussed. In addition, the book addresses appropriate criteria for estimating the accuracy of numerical results, as well as their importance for practical applications. Python code is provided with each chapter, and can be freely used and modified by readers. Moreover, numerous scattering results for different configurations are provided for benchmarking purposes. The book will be particularly valuable for those readers who plan to develop their own scattering code, and wish to test the correct numerical implementation of the underlying mathematics.
