The book is a result of the Advanced School Computational Acoustics, which took place at the International Centre for Mechanical Sciences (CISM), Udine, Italy, in May 2016. The aim of this book is to present state-of-the-art overview of numerical schemes efficiently solving the acoustic conservation equations, the acoustic wave equa tion, and its Fourier-transformed Helmholtz equation. Thereby, the different equations model both vibrational and flow-induced sound generation and its propagation. tion, and its Fourier-transformed Helmholtz equation. Thereby, the different equations model both vibrational and flow-induced sound generation and its propagation.
