Abstract: Edge region of HL-2A tokamak with closed divertor configuration is divided into meshes by a code combined with 2D fluid edge modeling code B2.5. Postprocessing code is provided. HL-2A tokamak edge plasma with about 3 MW auxiliary heating power is modeled and analyzed. It indicates that the plasma in front of divertor target plate exhibits high density and low temperature, and the divertor runs in conduction-limited regime, i.e, in high recycling mode.

Key words: auxiliary heating, edge plasma, modeling
