Hsu, C T

Fluid descriptions of toroidally confined plasma with FLR effects are studied, based on a generalized, energy conserving, self-consistent, nonlinear reduced fluid model (HHM). The model, derived via a fluid approach starting from moment equations, differs from Braginskii's fluid system in retaining O(rho/sub i//sup 2/) terms (where rho/sub i/ is the ion gyroradius) and most of the non-ideal effects. Hence, many of the well-known reduced fluid models can be reproduced from HHM by simply specifying scales of some parameters such as rho/sub i/ and ..beta... On the other hand, a Pade approximation of the full FLR system, obtained from the simplified version of HHM, is also presented.
