Shvets M. Thermophysical modeling of the moist vapour transport through the thin porous structures and semi-permeable membranes

The work is devoted to the creation of adequate models and the methodology of advanced thermoenergetic calculations and estimates at the study of perspective, from both the ecologic and energetic viewpoints, closed cycles of thermal engines. On the base of the performed in Dissertation analysis it was concluded that the conventional thermoenergetic approach to the description of any regeneration stirling-type cycles should be essentially modified. It was recommended to take into account the real impact of density on the main caloric functions of a closed stirlings (working between two given thermostats) such as enthalpy, internal energy, entropy. The Horstmann’s alternative formulation of Second Law has been used to argue the combined necessity of the thermophysical (i.e. presumably equilibrium) and thermoenergetic (i.e. mainly, dynamical and irreversible) considerations in any problem concerning the heat-mass-transfer through porous regenerator at the convective motion of a working fluid. The developed in Dissertation model is based on the electromagnetic-thermal analogy supposed between the respective closed contours. This approach looks promising since the further calculations of the velocity field (with its longitudinal and transversal components) can be occurred in the framework of the generalized Bernoulli equation. The new concept of the coupled Stirling-Rallis type of heat engine localized in the near-critical fluctuation range of carbon dioxide is proposed in Dissertation.
