项目摘要

As an undergraduate, I did a BSc in physics at the Universidad Autónoma Metropolitana in Mexico City, specializing in plasma physics. I then did a year in Paris studying a master's in physics focused on simulating magnetically confined plasmas. Through my early years, I became fascinated with the idea of fusion energy. Now, I am proudly starting a PhD, researching "Flexible Grids For Complex Tokamak Topologies" with Dr. Peter Hill.Magnetically confined fusion devices called tokamaks are one of the most promising devices to achieve commercial fusion. Their exhaust systems, called divertors, are of particular importance as the complex physics in that region sets the boundary conditions "upstream" for the fusion-producing core, and so ultimately the power production. Advanced divertor designs, such as the "super-X" and "snowflake" divertors can have complex magnetic geometries and topologies which can make simulating them a challenging task.The project's objective is to adapt and extend the world-leading open-source BOUT++ framework to better handle advanced divertor designs by developing and testing a new mesh implementation in C++. The new mesh will then be used to study the effect of the shape of these advanced designs on the upstream conditions and compare simulations to experimental results from the UK's MAST-U tokamak.

作为一名本科生，我在墨西哥城的Universidad Autónoma Metropolitana获得了物理学学士学位，专攻等离子体物理学。然后我在巴黎读了一年的物理学硕士，主要研究模拟磁约束等离子体。在我的早年，我对聚变能的想法着迷。现在，我很自豪地开始攻读博士学位，与Peter Hill博士一起研究“复杂托卡马克拓扑结构的柔性网格”。磁约束聚变装置（称为托卡马克）是实现商业聚变的最有前途的装置之一。它们的排气系统，称为偏滤器，特别重要，因为该区域的复杂物理学为聚变生产核心的“上游”设置了边界条件，从而最终产生了动力。高级偏滤器设计，如“超级X”和“雪花”偏滤器，可能具有复杂的磁性几何形状和拓扑结构，这使得模拟它们成为一项具有挑战性的任务。该项目的目标是通过开发和测试C++中的新网格实现，调整和扩展世界领先的开源BOUT++框架，以更好地处理高级偏滤器设计。然后，新的网格将用于研究这些先进设计的形状对上游条件的影响，并将模拟结果与英国MAST-U托卡马克的实验结果进行比较。
