Analysis of flow loss characteristics of slanted axial-flow pump device based on entropy production theory [PDF]
Royal Society Open Science, 2022 Slanted axial-flow pump devices are widely applied in urban water supply, irrigation and drainage engineering fields. The second law of thermodynamics is applied to investigate the flow loss characteristics of the 30° slanted axial-flow pump model ...

Thermodynamic Theory of Macrosystems: Entropy Production as a Metric [PDF]
EntropyThe article considers the description of a macrosystem in terms that do not depend on the nature of the macrosystem. The results obtained can be used to describe macrosystem models of thermodynamic processes, and to create interdisciplinary models that ...

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory
Energies, 2022 A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...

Microscopic theory for the time irreversibility and the entropy production [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2017 In stochastic thermodynamics, the entropy production of a thermodynamic system is defined by the irreversibility measured by the logarithm of the ratio of the path probabilities in the forward and reverse processes.

Towards Pragmatist Thermodynamics: An Essay on the Natural Philosophy of Entropy and Sustainability [PDF]
EntropyClassical thermodynamics (CT) has become integrated into everyday life, especially through its applications in engineering. In contrast, out-of-equilibrium thermodynamics (OET) is often viewed as a fundamental science that seems distant from daily ...
