Abstract
The article is devoted to the justification of the introduction of a flow thermodynamic potential to assess the maximum energy efficiency of gas systems in which there is no mechanical work, but a certain useful effect is realized: energy separation (vortex tubes), mass transfer and bubbling devices (cyclones, ejectors of various types), flow-through chemical reactors, plasmatrons, acoustic gas systems, Leontiev’s pipe, etc. Based on the results of the limiting energy theorem for gas systems, a relation for a thermodynamic potential of a special type is proposed. The thermodynamic flow potential has two equivalent forms: a potential as a function of the mechanical energy of the gas flow and a function of the internal energy of the gas flow.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
