Stefan-Maxwell Relations and Flow of the Heat for Turbulent Multicomponent Gas Mixes

A. V. Kolesnichenko


Abstract: Within the framework of the phenomenological theory of the turbulence multi-component сhemically active gas сontinuum the thermodynamic approach to closing of hydrodynamic equations of average movement at a level of models of the first order is considered. Оnzager formalism has allowed find determining equations for three main regions of turbulent flow: for the region laminar sublayer; for a buffer zone, in which the effects of molecular and turbulent transfer are comparable on the importance; for the region of an advanced turbulent flow. As an example a detailed conclusion of these equations for case of a small-scale turbulence is considered, in which tendency to an establishment local statistical isotropy is observed. In that specific case locally-stationary condition of an advanced turbulent field, when in a structure of a turbulence exists some internal balance, at which production of a entropy of a turbulent about equally it flowing, relations Stefan-Maxwell for a multicomponent turbulent diffusion and corresponding expression for a turbulent flow heat in a multicomponent сontinuum are received.
