论卡鲁扎磁流体力学的动力学基础
On the kinetic foundations of Kaluza's magnetohydrodynamics
摘要:
最近的研究表明,在单组分非平衡流体中存在相对论效应,对应于由电场引起的热通量。该工作中的处理仅限于四维闵可夫斯基时空,其中玻尔兹曼方程是用特殊相对论方法处理的。广义相对论的更完整的框架可以被引入到动力学理论中,以描述与电磁场相关的输运过程。在这种情况下,最初的卡鲁扎的形式主义是一个有前途的方法。目前的工作包含了卡鲁扎的磁流体动力学的动力学理论基础,并给出了一个新的描述建立热力学力超越了特殊的相对论描述。
英文摘要:
Recent work has shown the existence of a relativistic effect present in a single component non-equilibrium fluid, corresponding to a heat flux due to an electric field. The treatment in that work was limited to a four-dimensional Minkowksi space-time in which the Boltzmann equation was treated in a special relativistic approach. The more complete framework of general relativity can be introduced to kinetic theory in order to describe transport processes associated to electromagnetic fields. In this context the original Kaluza's formalism is a promising approach. The present work contains a kinetic theory basis for Kaluza's magnetohydrodynamics and gives a novel description for the establishment of thermodynamic forces beyond the special relativistic description.
