The purpose of the group is to study the properties of magnetically confined
fusion plasmas in the aspects of equilibrium, stability and nonlinear dynamics
by means of theories and numerical simulations based on the fluid models.
We mainly analyze the physical mechanism of the phenomena observed in the
LHD experiments. In the analyses, we investigate the stability limit of
the plasma and the effective particle supply method through the research
of self-organizing phenomena, disruptive phenomena, magnetic island effects
due to error fields, pellet ablation phenomena. Simultaneously, we develop
the model equations and the numerical codes to involve more realistic conditions
and we pioneer a new paradigm in the fluid plasma physics. The new knowledge
is utilized for the improvement of the original understanding and the investigation
of new mechanism for mysterious phenomena. By organizing the research results,
we aim to construct a comprehensive theory over the whole toroidal plasmas.
Foe this aim we also take the relation with other models such as transport
physics into account.
