Course Content
Basic equations of fluid dynamics, linearized Euler equations, speed of sound. Classical acoustics: the wave equation, solutions in Cartesian, cylindrical, and spherical coordinates. Fourier transform and convolution integrals, Green's function for the wave equation. Compact, noncompact sources. Lighthill's theory of aerodynamic noise: acoustic analogy, jet noise, scaling laws. Turbomachinery noise: duct acoustics, mode generation mechanisms, sound attenuation. Noise from moving bodies: helicopter noise, propeller noise, airframe noise. Computational aeroacoustics: high-resolution numerical algorithms, boundary conditions.
