This module has two parts. The first part, on turbulence modelling for computational fluid dynamics, is driven by Emmanuel Plaut (EP). It is focussed on the Reynolds Averaged Navier-Stokes (RANS) approach and models. Mathieu Jenny (MJ) will stand in for EP on this part - he already took over session 3.
The second part, focussed on general turbulence theory and Wind Energy, has been setup by EP with Joachim Peinke and Michael Hölling (MH) from the university of Oldenburg. It is now driven by MH.
All sessions and the exam will take place in room P318. The sessions of EP and MJ will start at 8:30 and finish at 11:45, with a break from 10 to 10:15.

In these lecture notes, some equations and figures are empty and should be filled or realized by the students themselves (`DIY' means `Do it yourself' !). You may ask a more complete version of these lecture notes by mail to EP.

In sessions 1 to 3, with EP and MJ, the students will use Matlab; in sessions 4 to 6, with MH, the students will use the statistical computing software R; in both cases, on their laptop.

Nous remercions la Fondation Mines Nancy et le programme Erasmus+ pour leur soutien, qui nous permet d'inviter MH à donner 3 sessions dans ce module, ainsi qu'une conférence générale.

Turbulent flow data sets

• Jet.txt : Velocity measurements in m/s with a sampling frequency of 8 kHz, from the laboratory experiment of Renner et al. (2001), an air into air round free jet; the measuring device is a hot wire

• Wind.txt : Wind velocity measurements in m/s with a sampling frequency of 1 Hz, from a metrological mast in North Germany (Peinke et al. 2010); the measuring device is a cup anemometer

• There are 3 other data sets on the ARCHE page
