By this course the students will be able to
be aware of importance of quitening aircraft for meeting international noise regulations
appreciate the fact that in noise studies sound waves are of really small amplitude and usually diverse frequencies
linearize the fundamental flow equations and obtain equations governing wave propagation
derive an inhomogenouse wave equation from the full non-linear Navier-Stokes equations and identify the sources of sound due to the flow
use Green's function for developing an analytical solution to the inhomogenous wave equation given its source, and perform scale analysis towards the radiated sound levels
understand physics of sound propagation through circular and rectangular ducts, and determine the frequencies and modal numbers of the propagating waves
analyze the pattern of rotor-stator interactional modes that result in turbomachines
understand the generation of sound by moving rotor blades, and propagation patterns of sound from these sources
understand the points one must always be aware of in using numerical approaches to solving aeroacoustics problems
appreciate basic jet noise generation mechanisms, and flight effects in jet noise radiation
