SINOPSIS

New equations that describe the behavior of fluids in nanochannels and take into account the molecular structure of the fluid and results of real and numerical experiments are presented. The Couette and Poiseuille flows are considered. The results obtained show the possibility of describing structural transformations in thin layers by the continuum mechanics methods. New degrees of freedom of the material are introduced via the second continuum that makes up for the role of the forming new phase of state. In the models considered the properties of the new phase are determined by the effect of rigid boundaries with a different structure.
