PA - C7 - MEC573 : Potentiel éolien, solaire, hydraulique

Domaine > Mécanique.




The atmospheric, oceanic and terrestrial environment could be an infinite source of energy for human activity. One of the main challenge for the next century is to develop renewable energy production with a low emission of greenhouse gazes. The goal of this course is to get the basic knowledge on physics and hydrodynamics at small and intermediate scale in order to quantify the aeolian, solar or hydraulic potential of a local or regional area. Independently of the technology and its efficiency what is the available power of a given environment ?  What is the availability and the variability or the energetic resource ? How could we match the variability of the natural energetic resource to the human activity ?

This course is divided in 3  lectures and 7 working afternoon devoted to a specific project using laboratory experiments, numerical simulations or data analysis.
