Near‐sonic plasma flows along magnetic field lines have been observed in the far scrape‐off layer of some tokamaks. Such flows are simulated with multi‐fluid edge transport code UEDGE and the results for Alcator C‐Mod and NSTX tokamaks are presented. The important role of asymmetric intermittent cross‐field transport and magnetic configuration in generating near‐sonic flows is highlighted. The effect of large parallel flows on divertor detachment and main chamber recycling is discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
