在最后一章中，G.I. 发表了两篇关于爆炸波的经典论文。泰勒介绍。这两篇论文的目标是提供一种相当简单的方法来确定原子弹释放的能量，并根据三位一体试验场得出的经验结果验证模型。为了估计释放的能量，使用了两种数学工具。第一个方法将代表守恒定律的偏微分方程简化为常微分方程，并对所得方程进行数值求解；第二种方法确定系统无量纲状态的近似代数形式，即 {f,ψ,ψ}。本章继续以数值方式解决更一般的守恒原理，并提供了与旋转恒星相关的爆炸相关的扩展示例，其中 G.I. 开发的两种方法。使用了泰勒和上面讨论的。
In this last chapter, two classic papers on blast waves by G.I. Taylor are presented. These two papers sought as their goal to provide a fairly straightforward method to determine the energy released from an atomic bomb and verified the model against empirical results derived from the Trinity test site. In order to provide an estimate of the energy released, two mathematical tools were utilized. The first reduces the partial differential equations representing the conservation principles into ordinary differential equations and solves these resulting equations numerically; the second method determines approximate, algebraic forms for the non-dimensional states of the system, which are {f,ϕ,ψ}. The chapter goes on to numerically solve more general conservation principles and provides an extended example related to blasts associated with rotating stars where the two methods developed by G.I. Taylor and discussed above were utilized.
