Abstract
Predictions of the scrape-off layer (SOL) plasma conditions from the 2D multi-fluid code EDGE2D-EIRENE are compared to the OEDGE 1D fluid code for JET low-confinement mode (L-mode) plasmas. In the low-recycling divertor conditions (divertor target plasma collisionality ), OEDGE and EDGE2D-EIRENE agree on the electron temperature, the ion temperature, and the electron density within 10% in the low-field side (LFS) divertor X-point region (divertor SOL) and within 25% in the LFS midplane region. In high-recycling conditions (), the predictions of both codes agree on the electron temperature within 20%, while differences in the ion temperature and electron density increase to as high as 50% in the divertor SOL.
