Meeting
Room
OFD-130
Organisation : Volker Naulin (volker.naulin@risoe.dk)
and Jens Juul
Rasmussen (jens.juul.rasmussen@risoe.dk),
Department of Optics and
Estimated number of participants 15 (incl. 10 PhD students)
Purpose:
Discuss the
status of the modeling of plasma turbulence and the associated anomalous
transport. In particular we will focus on the numerical modeling. There will be
tutorial lectures on turbulence, transport, zonal flow generations and
numerical methods.
The program
will be very informal with time for discussions of specific problems
In addition
to the overview/tutorial lectures by Volker Naulin, Anders Nielsen, Poul
Michelsen, Jens Juul Rasmussen, and NN, we suggest that the participating
PhD-students and others give talks presenting their work, results, and problems.
The
overview talks will cover:
Turbulence
in general.
Turbulent
transport and mean flow generation
Numerical
investigations of vortex dynamics and turbulence in 2D flows
Numerical modeling of turbulence in toroidal devices
Numerical
methods: spectral methods, finite difference methods, upwinding etc
Status of
nuclear fusion research
Please contact the organisers for further information and
registration. Funding is available for covering local expenses for a
limited number of students.
