为了验证流体模拟中引入的各种物理模型，需要对磁约束系统中的开场等离子体进行粒子模拟。开发了一种先进的粒子模拟程序PARASOL，该程序将二元碰撞模型与静电粒子池（PIC）方法相结合。详细介绍了仿真模型。给出了用PARASOL模拟得到的鞘层入口边界条件。研究了E×B漂移、扩散损耗和辐射冷却的影响。热沿磁场的输运也进行了研究。
Particle simulation of open-field plasmas in magnetic confinement systems is required to validate various physics models introduced to fluid simulations. An advanced particle simulation code PARASOL was developed, in which a binary collision model is incorporated to an electrostatic particle-in-cell (PIC) method. The simulation model is described in detail. Boundary conditions at the sheath entrance obtained by PARASOL simulations are shown. Effects of E×B drift, diffusive loss, and radiative cooling are studied. Heat transport along magnetic field is also investigated.
