Abstract

From the classical system of equations describing the transport processes a simplified system is derived (one fluid, two spatial dimensions) of flow equations for the density n, the parallel velocity v-//, the perpendicular velocity v-rho-c1 and the pressure p in the plasma boundary layer (Section 2). A code has been written for the solution to these equations, based on a splitting technique in spatial directions. Classical effects are taken into account and shown to be important: they lead to radial fluxes near the limiter tip of the same order (or even larger) of the anomalous ones usually adopted, resulting in a non- symmetric layer around the limiter. Another characteristic feature of this code with respect to other 2-D codes is the avoidance of any symmetry assumption along field lines. A JET-like plasma with one toroidal limiter has been considered in the computations reported here.
