Aeroacoustic scattering of rotating sources using a frequency-domain acoustic pressure gradient formulation Vrije Universiteit Brussel
In this paper, a frequency-domain methodology for acoustic scattering prediction from rotating sources is suggested. Frequency-domain acoustic analogy formulations are used for incident field prediction of acoustic pressure and the acoustic pressure gradient. The latter is required for evaluation of the hardwall boundary condition on the scattering surface. The boundary value problem is solved by the equivalent source method. The overall ...
