摘要

对涡度场张量和电磁张量进行了比较。尝试用几何代数语言使用双向量来表达涡度及其对偶。在几何代数语言中,所有四个流体麦克斯韦方程通过两种方式被简化为一个单一方程,即使用双向量 \(\textbf{F}\)和它的霍奇对偶 \(\mathbf{F^*}\),这些与电磁学中的相应结果类似。流体动力学中的复结构(\textbf{F}=\textbf{L}-I\textbf{W}/)是本文的一个新方法。同时还得到了麦克斯韦方程的多向量表示法和波因定向量的表达式。

Fluid Maxwell’s equations in the language of geometric algebra

A comparison of the vorticity field tensor with the electromagnetic tensor is done. An attempt is made to express the vorticity and its dual in the language of geometric algebra using bivectors. In the language of geometric algebra, all four fluid Maxwell’s equations are reduced to a single equation in two ways, i.e., using a bivector \(\textbf{F}\) and also its Hodge dual \(\mathbf {F^*}\), and these are analogous to the corresponding results in electromagnetism. The complex structure \(\textbf{F}=\textbf{L}-I\textbf{W}\) in fluid dynamics is a novel approach in this work. A multivector representation of Maxwell’s equations and an expression for the Poynting vector are also obtained.
