Hydrodynamics of polarizable liquids
The complete hydrodynamic theory of polarizable and magnetizable isotropic liquids is presented. Using only input of universal acceptance, the Lorentz transformation, the macroscopic Maxwell equations, and the thermodynamics, a set of hydrodynamic equations of motion is derived rigorously, without any ad-hoc assumptions or residual ambiguities. Definite expressions are especially provided for the total momentum density, its stress tensor, and the acceleration of a polarized body. Other controversial concepts, such as the field momentum density, the pressure, and the force density in the polarized body, are shown to be arbitrary, the extent of which, however, is clarified.
