11. Prerequisites



12. Recommended optional studies


Recommended optional studies are:


13. Course content


  • Introduction: the origin and nature of turbulence, methods of analysis, diffusivity of turbulence.
  • The statistical description of turbulent flow: the probability density functions, Fourier transforms and characteristic functions, correlation functions and spectra.
  • Mean flow equations for momentum and heat: Reynolds equations, Reynolds stress, turbulent heat transfer.
  • The dynamics of turbulence: mean and turbulent kinetic energy, vorticity, dynamics of turbulent fluctuations.
  • Free shear flows: turbulent wakes, jets and mixing layer.
  • Wall-bounded shear flows: flows in pipes and channels, boundary layers.
  • Turbulent Spectra and the scales of turbulent motion.
  • Examples of turbulent transport in geophysical fluids.


14. Recommended and required literature


  • Lecture notes;
  • Tennekes, H. & J.L. Lumley, 1972. A First Course in Turbulence. The MIT Press.


15. Activities and teaching methods in support of learning


Weekly lectures and exercises (individual work).


16. Assessment practices and criteria, grading scale


To pass the course, the students need to do 1/3rd of the exercises.

The exercises will contribute to 25% of the overall grade. The rest 75% will be determined by the final exam.
