Analysis of the microscopic-macroscopic structure in real fluid flow

This paper presents new results concerning the physical coexistence of the molecular chaosand the continuous determinism in real fluid flows. By using the FLUONS mathematical devices [1], the authors investigate the existence of a physical process called MOLECULAR COHERENCE. This particular kind of structure equilibrium needs the fulfilment of the conditions required by the increasing entropy and the minimum of the kinetical as well as the informational energy. Qualitative and quantitative results concerning the fluctuations in real fluid flows support this new point of view in Fluid Mechanics.
