Aeroacoustics

Learning Outcomes

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Model some complex noise generation problems.
• Appreciate the limitations of different modelling techniques,
• Synthesise theory from different fields of study (eg. fluid dynamics, acoustics, mathematical methods).
• Recognize and define terms specific to aeroacoustics.
• Use relevant mathematical methods to solve problems in aeroacoustics.

Cognitive Skills

Having successfully completed this module you will be able to:

• Improved ability to read and interpret scientific textbooks and papers related to aeroacoustics.
• Assess whether the complexity of a problem in aeroacoustics may be reduced, e.g. by the use of scaling laws.
• Analyse aeroacoustics problems and select appropriate methods for solution of the problems.

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Explain how mean flow and boundaries can affect sound generation and propagation.
• Understanding of some of the current state-of-the-art research in aeroacoustics.
• Discuss the generation and propagation of sound in fluids
• Apply aeroacoustics theory to new problems.
• Explain the principle of the Lighthill acoustic analogy, and how this is related to sound generated by turbulent flows
• Explain how scaling laws may be derived (for some simple examples), and to interpret these.

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Synthesise information from a range of sources.
• Communicate clearly in written reports.
• Ability to read, understand and interpret scientific papers.
• Apply critical analysis and evaluation skills.
• Write computer programs and reports.

Full CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• The course does not include purely numerical models, but does include a wide range of analytical and semi-analytical (i.e. analytical methods requiring numerical solution) methods for noise modelling. Both coursework assignments require the students to successfully apply these techniques to specific problems. The limitations of the methods are discussed in lectures, touched on in the assignment, but assessed primarily through the viva at the end of course.
• The material in this course is rarely found in undergraduate courses and is similar in level to our Advanced Course in Aeroacoustics we provide for industry practitioners. The two coursework assignments require the students to successfully apply the knowledge they have learned in the lectures. Both require the student to address the physical principles underlying the equations in addition selecting and applying relevant mathematical equations. At least one includes a section on making engineering judgments based on the maths/physics analysis.

Partial CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• The course is designed to keep engineering, maths and phsyics understanding in step. The communication of the underlying physical principles is assessed in the assignments which require a qualitative description of the results in addition to calculations. It is also assessed in the discussion section of the viva, which includes a verbal description of the results of one of the courseworks and a free discussion on an advance to the coursework itself that the candidate has not seen before.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
