本文利用新近开发的二维程序Q2 D研究了场反转组态（FRC）的输运现象，该程序将磁流体动力学程序与束流部分的蒙特卡罗程序耦合起来。用Q2 D方法模拟了平行于简单开θ-箍缩场的输运及其相关的外流现象，结果与一个前沿理论非常吻合，提高了Q2 D的有效性，同时加深了对这一基本过程的理论理解。我们发现一个鲜明的区别之间的演变的FRC和镜像等离子体的径向密度分布的运输过程的结果，支撑的FRC的封闭通量表面的至关重要的作用，以提高限制的镜子。我们的特点刮除层（SOL）运输包括镜捕获效应，我们发现在SOL的约束时间和离子碰撞时间之间的关系。Q2 D代码进一步阐明了基本的运输…
The transport phenomenon of a Field Reversed Configuration (FRC) is studied using the newly developed two-dimensional code Q2D, which couples a magnetohydrodynamic code with a Monte Carlo code for the beam component. The simulation by Q2D of the transport parallel to the simple open θ-pinch fields and its associated outflow phenomenon shows an excellent agreement with one of the leading theories, elevating the Q2D validity and simultaneously deepening the theoretical understanding of this fundamental process. We find a sharp distinction between the evolved radial density profiles of the FRC and mirror plasmas as a result of the transport processes, underpinning the crucial role of the closed flux surfaces of the FRC to enhance the confinement over that of the mirror. We characterize the scrap-off layer (SOL) transport by including the mirror trapping effects, and we find a relationship between the confinement time in the SOL and the ion collisional time. The Q2D code further illuminates the basic transpor...
