Summer School on Sustainable Aviation

Every year, UTIAS runs a Summer School in Sustainable Aviation in late May or early June. This two-day course provides in-depth coverage of a topic directly related to sustainable aviation. UTIAS CREATE trainees are required to attend this summer school, and other UTIAS students are strongly encouraged to attend. Participants from other units at the University of Toronto, as well as those external to the University, are welcome to attend, subject to the availability of space. The topics covered previously and to be covered in the future are:

2013 Atmospheric physics and life cycle assessment
2014 Aeroacoustics

For 2014, the fee for external participants is $300 early bird special and $400 regular; for students this is reduced to $200 early bird special and $300 regular. Those wishing to attend the Summer School should contact the CRSA administrator, Georgette Stubbs, stu...@utias.utoronto.ca.

Introduction to Aeroacoustic Theory

Aeroacoustics research relies heavily on several fundamental concepts involving the generation of sound by or in an unsteady fluid, and its propagation through a non-uniform medium from the source to the receiver. An introduction to the most important concepts will given to (a) provide a solid foundation on which to build more detailed understanding and to (b) prepare the student for the three subsequent discussions in this summer school. Those topics to be discussed will include:

  • Foundational elements of acoustics
    • Fundamental equations; Kovasznay’s modal decomposition
    • Uniform propagation in 1-, 2-, and 3-dimensions
    • Acoustic fluctuations in a non-uniform medium and ray theory
    • Green’s functions and multiple expansions
    • Kirchhoff’s formula
  • Sound generation
    • Elementary sources in a stationary medium
    • Multiple-scale, matched-asymptotic expansions for sound generation for slowly-developing free shear flows
    • Acoustic analogies of Lighthill and Goldstein

Coherent Structures and Jet Aeroacoustics

Turbulent jet noise is a controversial fluid mechanical puzzle that has amused and bewildered researchers for more than half a century. The intricate pieces derive from the disparate physics and scales of the energetic, turbulent jet flow and the weak, radiated acoustic field, and the way in which these two components of the solution of the compressible flow equations are connected. Research on linear acoustics completed the outer edges of the puzzle more than a century ago. Turbulence theory, experiment, and simulations have completed large sections of the middle. But despite 60 years of research in aeroacoustics, the remaining pieces have yet to be satisfactorily assembled.

The first part of the lecture will introduce aeroacoustic theory and review what it has and has not been able to explain vis-à-vis jet noise. Part two will address the issue of coherent structures: What are they? How can they be educed from experimental and numerical data? How can they be modelled? Can they provide a unified theory of jet noise? What prospects, if any, to they present for control?

Direct Noise Computations of Airfoils and Noise Reduction Approaches

  • Introduction:
    • How is aerodynamic noise generated?
    • A brief history of Direct Numerical Simulations applied to aeroacoustics
    • What type of aerofoil noise mechanisms do exist?
  • Computational approaches
    • What computational approaches exist for computing noise?
    • Numerical Challenges
    • Suitable Schemes and Boundary Conditions
  • Airfoil Noise Simulations
    • Tones and feedback loops
    • Additional Noise Sources (other than trailing-edge noise)
  • Noise reduction strategies
    • Serrations for noise reduction
    • Compliant trailing edges for noise reduction

Hybrid Methods for Aeroacoustic Predictions

An overview of computational methods for aeroa-coustics and hybrid techniques combining aeroa-coustic theories with flow simulations will be cov-ered. Topics will include: Lighthill’s theory and extensions, Ffowcs Williams-Hawkings equation, and their numerical evaluations; methods for in-corporating the effect of solid boundaries; high-fidelity CFD methods for acoustic source compu-tations; prediction and control of noise from air-foils, bluff bodies and turbulent boundary layers with surface roughness or discontinuities; and aeroacoustic source mechanisms.
