摘要：

The EDGE2D code with drifts can satisfactorily reproduce measured target asymmetries in the JET field reversal experiments. It also reveals the parallel flow pattern in the main scrape-off layer (SOL) region, which mainly consists of the ion Pfirsch-Schluter how and the return parallel flow caused by the poloidal E-r x B drift. Individual switches for the drifts in the EDGE2D enabled one to separate effects of various drifts. It was found that delB and centrifugal drifts cause the largest target asymmetries and SOL flows. However, E x B drifts were also found to produce the right trends in the asymmetries. (C) 2001 Published by Elsevier Science B.V.
