摘要 以二维边界等离子体流体模拟代码B2.5为核心,编制适合于具有封闭偏滤器位形特征托卡马克的边界层网格划分代码和计算后处理代码.模拟分析HL-2A托卡马克有约3MW辅助加热功率时的边界等离子体特性.结果表明,偏滤器靶板前形成了致密低温等离子体,偏滤器运行于高再循环状态. 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.
