Fluid dynamical Lorentz force law and Poynting theorem—introduction

Fluid dynamical analogs of the electrodynamical Lorentz force law and Poynting theorem are introduced. Analysis shows the fluid dynamical Lorentz force and Poynting theorem describe new channels of stress-energy propagation and dissipation due to the action of longitudinal and transverse modes of flow. These channels are important for describing stress-energy dissipation along curved stream tubes such as those found in turbulent flows. (paper)
