DYNAMICS OF A LIQUID WITH MOMENTUM ANISOTROPY

A dynamical model of a liquid with momentum anisotropy (LMA) is constr ucted using the ideas and principles of the momentum mechanics of cont inuous media. The equations for a lubricating layer are derived in the thin-layer approximation. Shear flow between parallel surfaces is con sidered. It is shown that a liquid with momentum anisotropy exhibits a dimensional effect in its viscosity and a kinematic ordering in the o rientation of the long axes of the molecules. The approach which has b een developed is promising for an adequate description of the theology of thin boundary layers which are formed close to a solid surface and determine the fundamental friction laws.
