项目摘要
Nonlinear Magnetohydrodynamic(MHD) simulations have been executed for a comprehensive modeling of collapse phenomena in toroidal plasmas. The edge-localized mode(ELM) in spherical tokamak, the core density collapse(CDC) in heliotron, and the helical structure formation in reversed-field pinch(RFP) have been examined, comparing with experimental observations. Several common natures such as the magnetic reconnections under the pressure gradient which cause three-dimensional relaxed structures have been found out.
已经执行了非线性磁流体动力学(MHD)模拟,以全面对环形等离子体中的崩溃现象进行了全面的建模。与实验观测相比,已经检查了球形托卡马克中的边缘量化模式(ELM),Heliotron中的核心密度塌陷(CDC)以及反向场(RFP)中的螺旋结构形成。已经发现了几种常见的性质,例如压力梯度下引起三维松弛结构的磁重连接。
