Abstract
AbstractPredictions 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.
