FLOW
code web page
The code FLOW has been
developed as a collaboration between the University of Rochester and the
Princeton Plasma Physics Laboratory. The purpose of the code is to study the
equilibrium properties of toroidal devices, such as tokamaks, in conditions
relevant to present day experiments
The most unique feature of
the code is the ability to study flow-dependent equilibria. Present day
experiments often show the presence of high macroscopic flow. An example of a
machine with large toroidal flow is the Princeton spherical tokamak NSTX, while
high poloidal rotation can be found in the UCLA Electric Tokamak ET. Despite the
obvious relevance of the study of equilibrium in the presence of strong flow,
little work has been done on the subject, in particular regarding poloidal
rotation, which constitutes a more difficult problem with respect to purely
toroidal rotation. To the best of the authors? knowledge, before the code
development no numerical work at all had been done on equilibria with poloidal
flow exceeding the poloidal sound speed. [R.

The code main targets
are:
1) The study of MHD and kinetic tokamak equilibria
with purely toroidal flow
2) The study of MHD equilibria in the presence of
arbitrary poloidal flow
