Davis, Stephen H. (ed.) et al., Annual review of fluid mechanics. Vol. 38. Palo Alto, CA: Annual Reviews (ISBN 0-8243-0738-0/hbk). Annu. Rev. Fluid Mech. 38, 583-512 (2006).
Summary: This article provides a critical review of computational techniques for flow-noise prediction and the underlying theories. Hybrid approaches, in which the turbulent noise source field is computed and/or modeled separately from the far-field calculation, are afforded particular attention. Numerical methods and modern flow simulation techniques are discussed in terms of their suitability and accuracy for flow-noise calculations. Other topics highlighted include some important formulation and computational issues in the application of aeroacoustic theories, generalized acoustic analogies with better accounts of flow-sound interaction, and recent computational investigations of noise-control strategies. The review ends with an analysis of major challenges and key areas for improvement in order to advance the state-of-the-art of computational aeroacoustics.
