Thematic Programme
CONCEPTUAL ASPECTS OF TURBULENCE
(Organisers: B. Dubrulle, N. Mauser, S. Nazarenko, A. Tsinober, A. Schekochihin)
Workshop and Minicourse
"Conceptual Aspects of Turbulence: Mean Fields vs. Fluctuations"
11-15 February 2008
This workshop brings together a number of researchers working on turbulence in fluids, MHD, and plasmas. As implied by the title, the goal of the workshop is to discuss the interaction between regular and fluctuating, large- and small-scale components in turbulent systems and to attempt to understand how - conceptually and practically - one might to attempt to break beyond traditional approaches and make progress in understanding turbulence in space, on Earth, in the laboratory, in the computer or on paper.
TIMETABLE
(see list of talks for full titles)
Note: Time allocated for long talks includes 10-15 min discussion
Minicourse tutorial lectures are in green (these are mostly blackboard style; they will typically start with textbook material and progress to the level of current research)
