摘要：
本文的目的是讨论的历史和起源拉格朗日流体动力学方法模拟冲击驱动流。大多数开创性的研究都发生在曼哈顿计划中。一系列拉格朗日流体动力学方案是由约翰·冯·诺依曼、鲁道夫·佩尔斯、托尼·斯克尔姆和罗伯特·里希特迈尔在1943年至1948年之间创建的。这些方案彼此之间差异很大;然而，它们都使用交错网格和控制方程中导数的有限差分近似，其中第一个方案是由冯·诺依曼提出的。这些突破性的方案主要发表在洛斯阿拉莫斯实验室的报告中，这些报告最终在作者身份几十年后解密，这促使我们记录这项工作，并在更广泛的科学界可以访问的论文中描述伴随的历史。此外，我们试图纠正历史遗漏的关键贡献Peierls和Skyrme创建强大的拉格朗日流体动力学方法模拟冲击驱动流。了解拉格朗日流体动力学方法的历史可以帮助解释许多现代方案的起源，并可能激发对新方案的追求。
英文摘要：
The intent of this paper is to discuss the history and origins of Lagrangian hydrodynamic methods for simulating shock driven flows. The majority of the pioneering research occurred within the Manhattan Project. A range of Lagrangian hydrodynamic schemes were created between 1943 and 1948 by John von Neumann, Rudolf Peierls, Tony Skyrme, and Robert Richtmyer. These schemes varied significantly from each other; however, they all used a staggered-grid and finite difference approximations of the derivatives in the governing equations, where the first scheme was by von Neumann. These ground-breaking schemes were principally published in Los Alamos laboratory reports that were eventually declassified many decades after authorship, which motivates us to document the work and describe the accompanying history in a paper that is accessible to the broader scientific community. Furthermore, we seek to correct historical omissions on the pivotal contributions made by Peierls and Skyrme to creating robust Lagrangian hydrodynamic methods for simulating shock driven flows. Understanding the history of Lagrangian hydrodynamic methods can help explain the origins of many modern schemes and may inspire the pursuit of new schemes.
