A Radiation-Hydrodynamic ALE Code for Laser Fusion Energy

多年来，核聚变能源一直被认为是清洁、安全的能源，未来几年，美国国家点火装置有望取得重大进展。如果英国要在随后的惯性聚变能演示器国际合作中发挥重要作用，我们需要有能力进行独立的目标设计和评估。英国学术界一直缺乏的一个关键组成部分是一个多维计算机模型，该模型通过激光能量的吸收、烧蚀、内爆和热核燃烧来跟踪激光目标的流体动力学演变。RALF（使用ALE方法进行聚变的辐射流体动力学）将在为期两年的项目中为这种能力奠定基础，如果需要参与重大项目，该能力可以迅速发展。RALF被设计成一个可扩展的并行计算机模型，能够在大型高性能计算（HPC）安装上以3D方式运行。RALF是华威大学和帝国理工学院之间的合作项目，并继续了从EPOCH代码和等离子体物理协作计算项目（CCPP）开始的合作领域。RALF将受益于AWE Aldermaston的密切联系和建议，在那里，用于发电的惯性聚变能源活动越来越多。

Fusion energy has promised clean, secure energy for many years and important advances are expected in the next couple of years from the US National Ignition Facility. If the UK is to play a significant role in a subsequent international collaboration for an Inertial Fusion Energy demonstrator we need the ability to make independent target designs and assessments.A key component of this which has been lacking in the UK academic area is a multi-dimensional computer model which follows the hydrodynamic evolution of the laser targets through absorption of the laser energy, ablation, implosion and thermonuclear burn. RALF (Radiation-hydrodynamics using ALE methods for Fusion) will lay the foundation for this capability in a two year project which can then grow quickly if required for participation in a major project. RALF is designed to be a scalable parallel computer model capable of being run in 3D on large High Performance Computing (HPC) installations. RALF is a collaboration between the University of Warwick and Imperial College and continues an area of collaboration begun with the EPOCH code and the Collaborative Computational Project in Plasma Physics (CCPP). RALF will benefit from close links and advice from AWE Aldermaston where there is a growing activity in Inertial Fusion Energy for power production.
