本文综述了自由表面等离子体面系统的分析和实验研究现状，为“先进限制-分流等离子体面系统”（ALPS）项目的进一步工作提供了一个良好的起点。启动ALPS是为了评估等离子体面系统改善性能和寿命的潜力。该项目的主要目标是证明先进的限流器/导流器系统在功率密度能力、组件寿命和功率转换效率方面优于传统系统，同时提供安全操作并最大限度地减少等离子体的杂质问题。迄今为止，大部分工作都应用于自由表面液体。已经组织了一个由几个机构组成的多学科小组来处理与这些系统有关的关键问题。先进的限制器和导流器的主要性能目标是峰值热通量达到50 MW/m{sup 2}，消除侵蚀的寿命限制，并能够以高功率转换效率（{大约}40%）提取有用热量。通过实验室实验、关键过程建模和概念设计研究，对各种方案进行了评估。
This review paper was prepared to survey the present status of analytical and experimental work in the area of free surface MHD and thus provide a well informed starting point for further work by the Advanced Limiter-diverter Plasma-facing Systems (ALPS) program. ALPS were initiated to evaluate the potential for improved performance and lifetime for plasma-facing systems. The main goal of the program is to demonstrate the advantages of advanced limiter/diverter systems over conventional systems in terms of power density capability, component lifetime, and power conversion efficiency, while providing for safe operation and minimizing impurity concerns for the plasma. Most of the work to date has been applied to free surface liquids. A multi-disciplinary team from several institutions has been organized to address the key issues associated with these systems. The main performance goals for advanced limiters and diverters are a peak heat flux of >50 MW/m{sup 2}, elimination of a lifetime limit for erosion, and the ability to extract useful heat at high power conversion efficiency ({approximately}40%). The evaluation of various options is being conducted through a combination of laboratory experiments, modeling of key processes, and conceptual design studies.
