Angular momentum conservation law and Navier-Stokes theory
A Navier-Stokes fluid is defined to be an isotropic, non-micromorph material for which a linear relation between the viscous pressure tensor and the stretching holds in every theoretical flow situation. However, as to the dynamical representation of this fluid's state quantities, the conservation law of angular momentum is generally ignored. The paper deals with the impact of this principle on the mathematical structure of the ordinary Navier-Stokes equation of motion. A respective new theory of thermofluid dynamics is briefly summarized. It allows the elimination of some serious inconsistencies which are inherent in the present state of the Navier-Stokes theory.
