AAE 61500 - Aeroacoustics


Credit Hours: 3.00. (ME 61500 ) Quantitative measures of sound (Decibel) scales, spectra, energetics of acoustic motions, and measurement techniques). The wave theory of sound (basic equations and properties, sound propagation in homogeneous and inhomogeneous media, one-, two-, and three-dimensional sound fields, and distributed sources). Effects of source movement. Aerodynamic noise generation-acoustic analogy (Lighthill’s equation and Ffowcs Williams-Hawkins equation). Introduction to Computational Aeroacoustics (CAA). Noise from turbulent shear flows (jet noise, cavity noise, and noise from flow over objects). Noise from turbomachinery, propellers, and rotors. Prerequisite: AAE 51100  or ME 50900  or ME 51300 . Typically offered Fall.
