摘要：
Two-dimensional simulation results are presented for the transport of plasma in the edge scrape-off layer region of KSTAR discharges by using B2.5 code. The code uses the classical model for parallel transport along the magnetic field and includes the cross-field drifts together with anomalous radial transport. The effects of drifts on particle distribution and divertor power dispersal are investigated and discussed. It is found that the drifts give rise to density spreading near the divertor, resulting in the reduction of heat load to the divertor. (C) 2007 Elsevier B.V. All rights reserved.
