dcterms:description
The direct correlation between classical mechanics of material points (Lagrange principle of classical mechanics) and classical continuum mechanics can be established when the existence of a trajectory and a friction force are added. This new approach to the fluid flow stability leads to the revision of the Rayleigh’s or Fjörtoft’s criteria and allows us to explain the discrepancy between the theory and experiments. As the example the Couette and Poisseuille flows are investigated and the discrepancies are explained.
