The acoustic analogy in four dimensions

International Journal of Aeroacoustics, 2019
The classical acoustic analogy theory is incomplete in the sense that the original research on the subject focused only on the prediction of acoustic pressure. There were no provisions for predicting the three components of acoustic velocity which are needed as input for aeroacoustic scattering applications. This is because the scalar wave equations of

The Acoustic Analogy and the Prediction of the Noise of Rotating Blades

Theoretical and Computational Fluid Dynamics, 1998
The paper focuses on the prediction of the noise of rotating machinery. The governing Ffowcs Williams-Hawkings (FW-H) equation for this problem is a wave equation for perturbation density with three source terms, which are known as thickness, loading, and the quadrupole source terms.
