abstract = {An improved version of the 2D multifluid code TECXY is used
to study the plasma parameters and the electric field in the
boundary layer of the TEXTOR-94 tokamak. An anomalous
perpendicular sheer viscosity eta (perpendicular to) is
incorporated into the ion momentum balance which allows to
fulfil the global (magnetic surface averaged) ambipolarity
constraint for the radial electric current, and to determine
the electric field in the transition layer by a second-order
ordinary differential equation for E-r(r). The code
modelling results suggest the existence of a narrow global
circulation layer for the poloidal plasma velocity just
inside the separatrix which is connected with a negative
electric field spike. PI proper choice of eta (perpendicular
to) gives better agreement with experimental velocity
profiles. (C) 2001 Elsevier Science B.V. All rights
