The article is the simulation of small size divertor tokamak edge transport barrier “ETB”. The modeling carries out with the multifluid transport code B2SOLPS5.0 2D with drifts and currents which was specially developed for simulation of tokamak edge transport barrier“ETB”. The emphasis is made on edge transport barrier “ETB”. The simulation demonstrated the following results: The “ETB” width has strong influence on the radial electric field. The E×B drift shear is function of “ETB” width. The ion parallel (toroidal) velocity has cocurrent direction and quite different for different “ETB” width. This difference is connected with the contribution of large E×B drift velocity in toroidal torque driven by pa... view more»
