论文摘要
该文档描述了一种数值算法，该算法通过Euler方法模拟3维空间中的等离子体和流体，其中空间网格固定在空间上。等离子体和流体穿过空间欧拉网界。 Euler方法可以代表血浆和流体的大变形。另一方面，当等离子体或流体被压缩到高密度时，应确保空间分辨率准确地描述密度变化。目前的3D Euler代码是为了模拟核融合燃料点火和燃烧而开发的。因此，3D Euler代码包括DT燃料反应，Alpha颗粒扩散，α颗粒沉积以加热DT燃料和DT反应的DT燃料消耗，以及基于三倍耐加压的流体模型的热能扩散。
The document describes a numerical algorithm to simulate plasmas and fluids in the 3 dimensional space by the Euler method, in which the spatial meshes are fixed to the space. The plasmas and fluids move through the spacial Euler mesh boundary. The Euler method can represent a large deformation of the plasmas and fluids. On the other hand, when the plasmas or fluids are compressed to a high density, the spatial resolution should be ensured to describe the density change precisely. The present 3D Euler code is developed to simulate a nuclear fusion fuel ignition and burning. Therefore, the 3D Euler code includes the DT fuel reactions, the alpha particle diffusion, the alpha particle deposition to heat the DT fuel and the DT fuel depletion by the DT reactions, as well as the thermal energy diffusion based on the three-temperature compressible fluid model.
