  In this Master thesis we investigate the influence of pressure anisotropy and
incompressible flow of arbitrary direction on the equilibrium properties of
magnetically confined, axisymmetric toroidal plasmas. The main novel
contribution is the derivation of a pertinent generalised Grad-Shafranov
equation. This equation includes six free surface functions and recovers known
Grad-Shafranov-like equations in the literature as well as the usual static,
isotropic one. The form of the generalised equation indicates that pressure
anisotropy and flow act additively on equilibrium. In addition, two sets of
analytical solutions, an extended Solovev one with a plasma reaching the
separatrix and an extended Hernegger-Maschke one for a plasma surrounded by a
fixed boundary possessing an X-point, are constructed, particularly in
relevance to the ITER and NSTX tokamaks. Furthermore, the impacts both of
pressure anisotropy, through an anisotropy function assumed to be uniform on
the magnetic surfaces, and plasma flow, via the variation of an Alfvenic Mach
function, on these equilibria are examined.
  It turns out that depending on the maximum value and the shape of an
anisotropy function, the anisotropy can act either paramagnetically or
diamagnetically. Also, in most of the cases considered both the anisotropy and
the flow have stronger effects on NSTX equilibria than on ITER ones. We
conjecture that these effects may have an influence on plasma stability and
transport, and play a role in the transitions to the improved confinement
regimes in tokamaks.
