Magnetohydrodynamic Equilibrium with Flow in Toroidal Plasmas and its Relevance to Internal Transport Barriers
The appearance of transport barriers in plasmas is usually taken to be the result of bifurcations in the transport equations, in which the possible control parameters is the radial electric field, in association with shear flow, which may contribute to the reduction or suppression of turbulent fluctuations. Yet, most calculations start from the assumption of magnetohydrodynamic (MHD) equilibira...
متن کاملNonlinear axisymmetric resistive magnetohydrodynamic equilibria with toroidal flow
The equilibrium of a resistive axisymmetric plasma with purely toroidal flow surrounded by a conductor is investigated within the framework of the nonlinear magnetohydrodynamic theory. It is proved that a) the poloidal current density vanishes and b) apart from an idealized case the pressure profile should vanish on the plasma boundary. For the cases of isothermal magnetic surfaces, isentropic ...
متن کاملTheory for explosive ideal magnetohydrodynamic instabilities in plasmas.
Flux tubes confined in tokamaks are observed to erupt explosively in some plasma disruptions and edge localized modes. Similar eruptions occur in astrophysical plasmas, for example, in solar flares and magnetospheric substorms. A single unifying nonlinear evolution equation describing such behavior in both astrophysical and tokamak plasmas is derived. This theory predicts that flux tubes rise e...
متن کاملNeoclassical Transport in Enhanced Confinement Toroidal Plasmas
It has recently been reported that ion thermal transport levels in enhanced confinement tokamak plasmas have been observed to fall below the "irreducible minimum level" predicted by standard neoclassical theory. This apparent contradiction is resolved in the present analysis by relaxing the basic neoclassical assumption that the ions orbital excursions are much smaller than the local toroidal m...
متن کاملPaleoclassical transport in low-collisionality toroidal plasmas
Radial electron heat transport in a low-collisionality, current-carrying resistive plasma confined in an axisymmetric toroidal magnetic field is hypothesized to be caused by the paleoclassical collisional processes of parallel electron heat conduction and radial magnetic-field diffusion. The electron distribution is Maxwellianized and the electron temperature equilibrated over a long length L t...
