Fall 2024 Lecture(AAE 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 fowcs Williams-Hawkings 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: ME 30900 or 51300 or AAE 51100.
Course ME 615 from Purdue University - West Lafayette.
