论文摘要
血浆鞘的多流体模拟越来越多地用于模拟从天体周围的全球磁层流到推进器和融合设备中的等离子体壁相互作用的各种问题。对于多流体问题，对解决经典护套的吸收壁建模的准确边界条件仍然是一个开放的研究区域。这项工作证明，使用真空边界条件以吸收墙壁，以表现出可比的鞘和连续运动鞘的较低矩之间的准确性。
Multifluid simulations of plasma sheaths are increasingly used to model a wide variety of problems in plasma physics ranging from global magnetospheric flows around celestial bodies to plasma-wall interactions in thrusters and fusion devices. For multifluid problems, accurate boundary conditions to model an absorbing wall that resolves a classical sheath remains an open research area. This work justifies the use of vacuum boundary conditions for absorbing walls to show comparable accuracy between a multifluid sheath and lower moments of a continuum-kinetic sheath.
