Description

Master’s Programme in Atmospheric Sciences is responsible for the course.

Module where the course belongs to:

  • ATM300 Advanced Studies in Atmospheric Sciences
    Compulsory for:
    1. Study Track in Geophysics of the Hydrosphere

    Optional for:

    1. Study Track in Biogeochemical Cycles
    1. Study Track in Meteorology

The course is available to students from other degree programmes.

Can be taken in the early or later stages of studies. The course will be offered every second year in the spring term.

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

Weekly lectures and exercises (individual work).

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.

The course will consists of lectures and exercises, and at the end of the course there will be an exam.
