Numerical analysis of the SOL/divertor plasma flow with the effect of drifts

The effects of drifts on parallel plasma flows have been studied. Numerical calculations using a 2D edge plasma simulation code (the SOLPS 5.0 code) have been done for the analysis of JT-60U W-shaped divertor plasmas in the detached state. Although significant effects of drifts on parallel plasma flows have not been observed in the inner and outer divertor regions, the flow reversal due to drifts has been observed at the outer mid-plane. The Pfirsch-Schlüter flow possibly explains the flow reversal.
