Abstract Predictions of the scrape‐off layer (SOL) plasma conditions from 2D multi‐fluid code EDGE2D‐EIRENE are compared to OEDGE 1D fluid for JET low‐confinement mode (L‐mode) plasmas. In low‐recycling divertor (divertor target collisionality ), and agree on electron temperature, ion density within 10% in low‐field side (LFS) X‐point region SOL) 25% LFS midplane region. high‐recycling (), predictions both codes temperature 20%, while differences increase as high 50% SOL.
Abstract The hydrogenic two‐point model (H‐2PM), an analytical for the scrape‐off layer that predicts a common electron and ion temperature density along flux tube from target density, is adapted to single‐species helium (He) model, preserving 2PM assumptions nature. Across range of densities heating powers, predicted within upstream measurements by high‐resolution Thomson scattering (HRTS) low‐confinement He plasmas performed in JET ITER‐like wall (JET‐ILW). For high‐recycling conditions,...
