教学目标 Course Objectives
The students are expected to analyse and solve a range of practical problems associated with aeroacoustics.
Examples include modelling of sound waves propagation and noise sources from jets, aerofoils, combustion, etc.
and exploring ways to reduce noise either at the source or through acoustic damping along the propagation path.
Upon completion of this module, students would be well placed to pursue research in the area of aeroacoustics and
related fields, and should understand
• how sound is generated, and how sound levels (pressure, energy, etc.) are measured;
• how sound waves propagate in free space, at discontinuities, and within pipes and resonators;
• and be able to model sound sources for various aeroacoustic problems and design for low noise.
