Resistive drift-Alfven turbulence in a tokamak edge plasma

One looks into behavior of turbulent flows in the resonance point vicinity within two-dimensional layer of tokamak edge plasma on the basis of the analysis of the nonlinear MHD-equations. The calculations show decrease of turbulent flows of particles and heat for electrons with increase of ion temperature at plasma edge. Decrease of the mentioned flows is shown to result from initiation of stabilization mechanism due to the rise of E x B drift rate shear the increase of which results from the rise of the ion pressure gradient. Besides, one looks into the effect of magnetic field on the turbulent transfer. Increase of the field is shown to result in suppression of the near-the-wall turbulence
